intel dual netwokcard problem on epia-m

[Niki Waibel]

i have the same problem

PCI: No IRQ known for interrupt pin A of device 0000:02:04.0. Please try using pci=biosirq.
PCI: No IRQ known for interrupt pin A of device 0000:02:05.0. Please try using pci=biosirq.

with the linuxbios + the new generated irq_tables.c.

no matter if i use pci=biosirq or not (does this kernel option
affect the functionality of a linuxbios system at all?).

i get this from linuxbios:

it seems that 02:04.0 and 02:05.0 are detected...
so what goes wrong?
there is no ``Assigning IRQ XX to ...'' for 02:04.0 and 02:05.0 in linuxbios...

it is strange to me that all this worked with a regular (singleport) intel
ethernet card!
