This looks like a problem with the PCI to PCI bridge code.
AFAIK, nobody checked whether it really works with several
such chips (I couldn't afford to buy two multi-port Ethernet
cards just to test this, for example :-)

Please boot the system again, with the two port and the 
four port card inserted, but enter "-v" at the "Boot: "
prompt this time ...

I'm too tired to explain the interrupt stuff right now,
but I already wrote something (for a system with an AH3940 
card) which seems to apply in your case too.

If you have access to the PCI 2.1 spec, then check out the 
section about PCI to PCI bridges and the suggested method of 
connecting PCI IntA .. IntD to the ISA interrupt controller.

More tomorrow ...
