Laptop ACPI issues

[Bill Christiansen]

Put both acpi=force and pci=noacpi in your /boot/grub/menu.lst:

title UBUNTU, normal mode
#:0 <-- type: 0 => linux, 1 => windows, 2 => other
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.8.1-3-686 root=/dev/hda1 ro acpi=force
pci=noacpi vga=791 quiet splash
initrd		/boot/initrd.img-2.6.8.1-3-686
savedefault
boot
