Interrupts still doesn't work?

Try cat /proc/interrupts or /var/log/messages to see if it get

Hey, actually boots (better than 2.6.19)!
with HT_IRQ turned on yields:

sh-3.1# modprobe ib_ipath
PCI: No IRQ known for interrupt pin C of device 0000:40:01.0. Probably
buggy MP table.
mtrr: type mismatch for fd500000,100000 old: write-back new:
ib_ipath 0000:40:01.0: mtrr_add()  WC for PIO bufs failed (-22)
ib_ipath 0000:40:01.0: infinipath0: Write combining not enabled (err
22): performance may be poor

Note that HT_IRQ removes the complaint (formerly right before
the mtrr complaints):

ipath_core 0000:40:01.0: infinipath0: irq is 0, BIOS error?  Interrupts
won't work

Further fun stuff to try?  I am your board monkey.
