I took some of Tim F. 's advice and I've found that I
am having some lower-level ethernet issues.
After I switched IP's and cables, the non-working interface was
working so I don't think the card is the problem.
It seems that when I plug any of these cards (3c905B-TX or 3c595)
into an 10Mbs or 10/100Mbs hub, I get a partition LED.
However, If I plug the same cards into a 3Com 100baseTX Hub, no such
problem. Could it be the packet sizes ?

Yes it is (err, was). I used that distro/kernel extensively as a
basic router.

(And it should be already).
On 5.x boxes, you can set IP forwarding (routing) on in the config
file:
/etc/sysconfig/network

Yep, both pci - that's part of the magic of pci: shared interrupts.

Yuk, why run that hagged old protocol if you don't need it?

Turn on routing in the kernel seems like one thing to look at, but
it probably isn't the only thing going on.
