No, these are standard Intel PCI cards.

I don't know if the kernel has anything to do with these problems or
not.  For right now, I'm stuck with the 2.4.9 kernel because the newer
ones have issues with the SCSI controler (Symbios Logic 53c1010).  The
kernel panics because it cannot find a harddisk.

I've done this as well, but the driver loads after insmod and negotiates
the connection, but no data will go over the wire.  This is the same
behavior I found with the e1000 (gigabit) driver, for a e1000 card.  (I
have not found a gigabit card for the alpha either).
