"Probably buggy MP table." on a ServerWorks mobo.

Hello!

I have salvaged a "Sun GigabitEthernet/P 2.0" adapter from a retired Sun
box which I thought I'd to put to some good use. But...

Insmoding the sungem driver fails with the following messages:

First try:

Aug 3 15:35:27 olivia kernel: sungem.c:v0.97 3/20/02 David S. Miller (davem@redhat.com)
Aug 3 15:35:27 olivia kernel: PCI: Enabling device 01:02.0 (0014 -> 0016)
Aug 3 15:35:27 olivia kernel: PCI: No IRQ known for interrupt pin A of device 01:02.0. Probably buggy MP table.
Aug 3 15:35:27 olivia kernel: eth2: Sun GEM (PCI) 10/100/1000BaseT Ethernet 00:00:00:00:00:00

Second try:

Aug 3 17:55:58 olivia kernel: sungem.c:v0.97 3/20/02 David S. Miller (davem@redhat.com)
Aug 3 17:55:58 olivia kernel: PCI: No IRQ known for interrupt pin A of device 01:02.0. Probably buggy MP table.
Aug 3 17:55:58 olivia kernel: gem: SW reset is ghetto.
Aug 3 17:55:58 olivia kernel: gem: GEM has bogus fifo sizes tx(-64) rx(-64)

So, any gurus out there who can speculate in what when wrong and what to
do about it?

Any hints on how to get this beast working is greatly appreciated, please
CC me as I'm not on the list.

Regards,
Fredrik

So, any guru's out there who can lend me a helping hand?
