What do the LEDs an the switch indicate?

You did not say what brand of NIC the tulip cards are, if Linksys, the
yellow LED might indicate a 100Mb/s link.  What does mii-tool tell you
about eth2?

If you switch cables between eth1 and eth2 and correct the IP addresses
accordingly, does eth2 work?  If so, look for a cable or switch port
problem.  If not then it's probably the NIC.

Sharing the IRQ should be OK.

Did you move the cables as well?  This sounds like, at least, the 101
and 103 subnets are "connected" together at the switch.

I noticed your other post concerning the NMI.  Has kudzu stabilized as
far as the internal NIC?  What is in your /etc/modules.conf?
