Well, it's tomorrow now.

I had a similar problem with an old Stallion board. First, if it's PCI
machine and ISA card, make sure that the BIOS hasn't thieved the
interrupt for one of the PCI devices (hit Del at startup, most PCI
setups have a "PCI" section nowadays). If it's a PCI card, make sure
there's an interrupt for it to claim (but BIOS should complain
otherwise).

I also dealt with a taiwanese PC-COM-8 card, featuring 8x16550 and an
interrupt latch (hey, the original had 8x16540!), which was set up to
autodetect interrupts, which didn't work. Explicitly specifying the IRQ
_did_ work.
