It may be that your BIOS is breaking acpi.
The standard advice is to start switching off as many things as possible using boot codes (eg nousb see wiki). (Though I thought if you were trying failsafe that already did that - are you sure you are entering boot codes correctly? There is no error message for an incorrect bootcode - I've long thought there should be).
You could try upgrading your BIOS as well if there is a new version.
