pirq tables of factory bios are very often incomplete or wrong.
One reason is that pirq and mptable are not used by the OS 
when ACPI is active. (Well, talking Linux) So this is an untested 
(and usually unused) path.

USB should get an IRQ, audio as well, probably. Don't think you need one
for VGA? What does your factory bios say?

Nope. you have to write support in form of mptable, pirq or ACPI to get
this working.
