Thanks for the acpidump.
The ASL below confirms your observation that with this version of the BIOS,
OSI(Linux) is a NOP for the HP dv9000, for OSYS is immediately overwritten
after it is first set.
I don't know what the issue is with the IOAPIC.
It is hard to believe that HP, Quanta, and AMD
intend that box to run in PIC mode, since it is multi-core.
(insert plug for Intel chipsets here:-)
