read my mail. I said that openbios can set the motherboard type, and Linux
can pick it up. Read my mail.

No kidding. read my mail. The BIOS can tell Linux what type the
motherboard is via the PARAM method already used to communicate memsize
and other vital stuff.
Once you know the motherboard type, you can do IRQ assignment in the
OS. And as experience is showing us here, you can probably do a better job
than the BIOSes out there.
