However, I'm still having problems... as you can tell, I'm pretty new to this, so I guess I'm not doing it right. I've succeeded at booting Ubuntu from my memory stick, going into "Try Ubuntu 10.04" mode, and then installing the applesmc files.
Then I click the "Install Ubuntu 10.04" icon. The first few steps are fine, but at the partitioning step, no partitions appear in the partition list, i.e. it still doesn't seem to find the hard drive.
Could someone please tell me what I'm missing here?
The reason you would want to install Ubuntu to an USB stick (not just boot the livecd, but actually install it to the USB stick), is to be able to easily test/compile kernels to fix the issue. Running Ubuntu from USB stick is very slow compared to normal.
I have the same problem with my macbook pro 7,1.
Can I do anything to help to fix the problem?

Thank God I found this thread. I have been struggling with this on a new MBP 13" for the last 4 days, trying all manner of old isos and hacks.
I am trying to use wubi in my bootcamp partition, so that I don't have to do any rEFIt messiness. (I have a mini that I triple-boot, but I am not willing to go through that setup again.)
Wubi is failing for the same reason. At least now I know that I can put this on the back-burner, as it is nothing that I am doing wrong. Virtual Box will have to suffice until this is resolved.

According to the Launchpad site, this bug now has a high priority. It has been confirmed that there are some issues with the NVIDIA MCP89 SATA chipset/drivers that control both the HDD and CD/DVD drive.
Only workarounds for right now:
1) Install Ubuntu on a USB stick, boot from the USB stick.
2) Boot the Ubuntu CD from an external CD-ROM drive.
3) Run Ubuntu in a VM. (not an option for native performance)
