I'm admittedly answering without reading your message in full
detail.  But did you dig the archives before posting (or do you
follow -mobile on a regular basis) and see the thread on
PCI->PCMCIA bridges lately?

In late July I asked if "bridging is general enough a
functionality so one could expect it to work in many / most
combinations".  Warner Losh promptly replied with interesting
points to obey in <[email protected]>.
Reading about the "PLX" chip a currency / voltage issue might
be your problem.  Can you try a combination of a bridge and a
card from _one_ vendor?  Is your combination designed to work
(suggested by the vendor(s)) or did you "somehow plug them
together" after you grabbed the pieces?
