If you want to disable the apm stuff at the kernel level, assuming you
are using Grub, try adding:

apm=off

to the kernel line.

Here's a sample of my grub entries:

title Fedora Core (2.6.10.hydranuke)
  root (hd1,0)
  kernel /vmlinuz-2.6.10.hydranuke ro root=LABEL=/ apm=off rhgb
ramdisk_size=8192000
  initrd /initrd-2.6.10.hydranuke.img


You can also add the ramdisk bit as well -- can't hurt.

Something weird with my computer -- it won't boot Linux with apm. its
BIOS is probably flaky, and I'm too chickenshit to do a BIOS upgrade for
obvious reasons. That single entry saved the day at a time I was not yet
adept at rebuilding kernels and I never bothered to change it since.
