Thanks, I'll have a look at these tomorrow. For some reason, ACPI on my
system doesn't work (produces the error I had before) if the base is set
to 0x500, but it does work with 0x400 (the factory slot). Also, a quick
peak at your irq_tables.c tells me they're probably no good, the correct
IRQ router is 0x3227, not 0x596. I'm not sure if your acpi tables would
do any good on my system or not, where they're entirely different
northbridges, but can't hurt to give it a whirl.
