How can I stop all power management stuff on my broken Ubuntu installation?

I have a fresh installation of Karmic Koala which keeps freezing very soon after login. I had this problem before with the same machine and the previous time I believe I solved it by booting up in safe mode and disabling all power management software, and then rebooting. However, I can't remember how I disabled the power management stuff. I don't remember if it was APM or ACPI or what.

"I just had to do this recently, here is what I did.

At the grub menu selection screen,
highlight the kernel command line and
press ""e"" to edit that line. Add
acpi=off to the end of the line, press
enter then b to boot your computer.

The change you have just made is for
this session only. To make it
permanent (if it solves your issue),
edit /boot/grub/menu.lst to include
this option.

In Karmic, I believe they've done away with menu.lst, but you just need to add ACPI=off to whatever they use for the grub config (/boot/grub/grub.cfg I think).

Good luck"
