I do not see anything, not sure about kernel panics.

Grub/Ubuntu do not use boot flags, but some BIOS need a flag. But that is not related.

You have lots of kernels, most now from old system. You may want to houseclean and or limit the number of kernels shown in menu.lst when you can get back into your system.
## e.g. howmany=all
## howmany=7
# howmany=2

The best I can suggest someone else may have a better solution is to chroot into your system and run full updates to refresh it, but that may just be where you are at?

kansasnoob's change sda5 to correct partition
sudo mount /dev/sda5 /mnt && sudo mount --bind /dev /mnt/dev && sudo mount --bind /proc /mnt/proc && sudo mount --bind /dev/pts /mnt/dev/pts && sudo cp /etc/resolv.conf /mnt/etc/resolv.conf && sudo chroot /mnt

# new for lucid & karmic
dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl

Then run a full set of updates:
Commands once in chroot:
#houseclean
apt-get autoclean # only removes files that cannot be downloaded anymore (obsolete)
apt-get clean
#refresh
apt-get update #resync package index
apt-get upgrade #newest versions of all packages, update must be run first
#would upgrade you to the latest kernel in the repositories
#dist-upgrade is also able to remove existing packages if required
apt-get dist-upgrade
apt-get -f install
dpkg --configure -a

I tried all the above and no difference. I also tried going into synaptic and reinstalling linux-image and grub, but to no avail. Any other ideas? Is there no way to just use the live cd to boot directly into my old install? What else can I try?
Thanks
