Probably most boards enable USB. The irq_tables.c for each mainboard has the IRQ map in it. I believe this file can be generated automatically if you boot using the stock BIOS and run the generator tool. I am working mostly on a system without a standard BIOS and am coddling this file together manually. Either way, take a look at it to get an idea of what it does. There have also been a fair number of posts related to constructing this file, so search the archives too.

Thanks. I plan to boot from SATA and not from USB. Do any other boards supported by LinuxBIOS (whose source is available in the source tree) bringup USB that I could use as a reference?

Then the Linux kernel will detect it and be able to attach the appropriate driver. -Jonathan
