Never mind! I solved it. I got the wrong IRQ assign to the NIC but thats
because...

smp_write_intsrc(mc, mp_INT, MP_IRQ_TRIGGER_LEVEL|MP_IRQ_POLARITY_LOW,
m->bus_8132_2, (3<<2)|0, m->apicid_8132_2,0x0);

when I assign a 0x0 in that line I actually get irq 31 assign to the
NIC. So I guess there is some sort of conversation to do here because
what I need is IRQ 5 for the NIC not 31 (even if 31 seems to work fine).

THX,
Knut Kujat.
