[4294667.296000] ACPI: BIOS age (1997) fails cutoff (2000), acpi=force is required to enable ACPI

Ok, there's the problem. Your BIOS claims to be from 1997, with the result that Linux will ignore it. Editing /boot/grub/menu.lst and changing the line starting 

#kopt

to have acpi=force at the end, and then running

sudo update-grub

should improve things. If you can attach the output of

sudo dmidecode

then there's a chance that we can whitelist your hardware.

** Changed in: acpi (Ubuntu)
Sourcepackagename: acpi => linux-source-2.6.15
Binarypackagename: acpi => None
     Severity: Normal => Wishlist
