That makes it an older board.

That's an FPGA part number.  I don't know what a FPGA would be doing on
a four port NIC... do you see other transceiver chips?

Yup, a PCI bridge.

  I'm trying to get all fours ports to

The driver doesn't assign IRQs, the BIOS (or OS) does.

Where/when did you pick up the 0.93 driver?  The standard one is 0.95.
No matter...

Errrmmm, no.  The driver actually goes to a great deal of effort to
reverse the common BIOS bug that incorrectly claims that the devices
behind a bridge are on separate IRQs.  The driver finds the first port
and copies the IRQ to the other ports.
