I was able to reproduce the problem even when the 4-port e1000 NIC
is plugged directly into the motherboard, so it's not the
riser...

I also tried with a 4-port VIA-Rhine NIC (router-board 44).  It also
fails it's third interface, with the same problem.  So, it is not
the e1000 NIC nor the e1000 driver that is the problem.

I do notice that it is the same interrupt (26) that is always assigned
to the broken port.  I have the lspci and dmesg output for the via-rhine
boot if anyone wants it...
