Are you sure that the BIOS for the second card is disabled or
in a region that doesn't conflict with any other card in your
system.  I've seen the same sort of symptom when the BIOS region
overlapped an ethernet cards shared mem location.  The IRQs must 
not be shared for EISA versions of this card (I know you've tried this).
What IRQs are you using?  Are you sure that nothing else is using
those IRQs?

Can you try the latest SNAP-shot floppy?  Its not quite the latest
code, but it is much closer than 2.0.5.
