blah, I've got a free IRQ under 9 (5), but neither the SCSI or the
network card get configured there :-(

Well, I assume the problem arises because it's sharing a NIC IRQ with
a SCSI IRQ (the ahc driver reports unknown SCSI commands with hex dumps).

I expected that, but I didn't expect it to shut the thing down because of
a conflict...won't even go single user.
