[coreboot] dbm690t PIRQ table

Has anyone tested the PIRQ table generated by the dbm690t code?

With a really trimmed down kernel, no ACPI and IO_APIC disabled the kernel goes looking for the PIRQ table. It finds one, but something isn't right the interrupts don't get routed. ( I really LOVE how there are three different ways to get the same information. )

Comparing the generated PIRQ to one pulled from my BIOS, they are nowhere near similar. I've tried replacing the dbm690t PIRQ table generator with a table from my BIOS, but it tells me the CRC is wrong. Something smells a little fishy. 

The mptables are very similar as expected. By telling the kernel to use the advanced IO_APIC, I can finally boot to a prompt. 

Next issue to resolve... X11 with fglrx...
Is this the right list to post FILO patches?

I've attached my PIRQ and MPtables for your reading enjoyment.
