Buggy ACPI BIOS

Hello people,

I seem to be stuck with this no-name desktop PC that has a buggy ACPI 
BIOS from Award. Although 5.2.1 runs fine on it (after disabling APIC), 
I get the following output from iasl:

Can anyone suggest how to fix my ASL (see below)? These errors don't 
seem to be mentioned in the handbook section on ACPI. I have the 
following info in case it is useful:
