Thanks BugBear,
The request was for plucky, who posted results from running 13.04 (with a pae kernel).
Your previous post shows that you can probably do the same, and there are several paths to follow.
A. If you want to keep your present installed system untouched, it is probably easiest to install 'grub-n-iso' from
https://help.ubuntu.com/community/grub-n-iso
to a USB pendrive and boot a live session.
B. but if you want to upgrade your system, you can do it according the instructions by mörgæs at
http://https://help.ubuntu.com/community/PAE
Actually in this case it is enough to install
1. fake-PAE and
2. a pae kernel,
3. boot with the pae kernel and
4. run
to find out if the computer now has 36 bits physical address size.Code:cat /proc/cpuinfo
And with your cpuid spec. it is enough to be able to report the test result with your Celeron CPU.

I have reverted back to Xubuntu 12.04.2 as this is my test machine.Code:cpuid|grep ^00000001 00000001 000006d6 00000816 00000180 afe9f9bf
Do you need it to be running 13.04?

No, according to my tests, cpuid gives the same information independent of the OS and/or kernel version. By the way, it is the same data as from my Pentium M, with 1.7 GHz (so it should basically be the same CPU, maybe only the clocking is different).
Thank you for testing and sharing this information about your CPU
Hello
I ran with kubuntu 13.04 and a non-pae kernel from linux-image -3.2.0-32-generic of previous version.
I then used fake-pae to install the latest PAE linux-image-3.8.0-26-generic successfully.
But the problem is that this kernel checks PAE presence during boot sequence, so I cannot use this kind of kernel.
So I don't really see the usefullness of fake-pae to force installation if the PAE test cannot be skipped at boot ?
my machine is thinkpad x40

Welcome to the Ubuntu Forums
This is a new problem or a new way to run with fake-PAE. Are you running an installed system with fake-PAE installed from the PPA? If so, either you have a version of Pentium M, that has not really all it takes to run PAE, or some developer has made the PAE checking tougher, to make it impossible to use fake-PAE to run Pentium M with new kernels.
Edit: Or maybe the problem is somewhere else in the computer (probably on the motherboard). I am running the same kernel 3.8.0-26 (Lubuntu 13.04) right now in an IBM Thinkpad T42 with Pentium M and fake-PAE successfully. I'm checking the version right now.
1. The cpuid code is slightly different, from what I have seen before.
2. I see that you have the PAE flag, I understand from fake-PAE.
3. You show 32 bits physical address size, where we have seen 36 bits with fake-PAE.
It would be very interesting share the result, if you download and try the 'grub-n-iso' original version of Lubuntu 13.04. Will it boot?

Thank you 7bit, sudodus and others working on this. I started following Launchpad bug 930447 soon after I upgraded to 12.04.
Today I followed the advice in post #43:
Installed fake-PAE (using post #12)
Installed a pae kernel, the one with the same version number as the non-pae I was running (using Synaptic Pakage Manager)
Rebooted using the new kernel (Kernel Linux 3.2.0-49-generic-pae)
Then I ran:
andCode:cpuid|grep ^00000001 00000001 00000695 00000812 00000000 a7e9f9bf
Everything seems to be working OK. I now feel confident that I will be able to upgrade to later versions of Ubuntu and not have to retire this computer when support for 12.04 LTS runs out in 2015.Code:cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 9 model name : Intel(R) Celeron(R) M processor 1300MHz stepping : 5 microcode : 0x45 cpu MHz : 1298.853 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : pae fpu vme de pse tsc msr mce cx8 mtrr pge mca cmov clflush dts acpi mmx fxsr sse sse2 tm pbe up bts bogomips : 2597.70 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 32 bits virtual power management:
Thanks again for all you have done.

I'm glad that our fake-PAE works for you, naildeca
I am pleased to report that this worked on my Thinkpad R51-2888. 12.04 wouldn't boot either so I started with 11.10. I've brought it up to 12.10 and am happy with it under XUbuntu. Had to disable the intel hardware video acceleration to get some GLX things to quit complaining but everything works great! I'm debating on taking it up to 13.04. The installer says it will disable any custom PPAs, so will that kill me? I'm a reformed BSD guy, so a lot of the Ubuntu stuff is unknown to me.
