the code is sort of similar, so maybe this could be done. Here are the main 
differences:

 (1) the PCMCIA card uses memory mapped IO in contrast to the PCI/ISA drivers
 (2) the PCMCIA card does not do DMA [at least not on my computer] so there is 
an extra part in the driver for doing PIO.

I also experienced some difficulties with a few other parts of the PCI/ISA 
driver code and this PCMCIA board. The microcode can be shared in any case.
