Last Kernel that is working for me is 2.6..31-17 from ubuntu ppa.
Trying latest kernel version 2.6.33-RC6 from mainline ppa I got a kernel panic.
A screenshot is attached.

Kernel Panic 2.6.33-RC6
hm, it doesn't seem to be an acpi-specific bug.
Can you please set the terminal to 50-rows mode so we get to see all of the oops? Use `vga=extended' or something from Documentation/x86/boot.txt and Documentation/svga.txt, thanks.

This is what I get with new RC7. It has some more details.
With official release 2.6.33 issue is resolved.
