Thanks for the pointers. I will look into implementing SPI support for these cards in a week or so. Ping me if you don't see any code/questions until then.
Here is the code for a simple mmap based interface to the card. You'll need to check lspci -v for the appropriate reg_addr and reg_len variables; the detection code is quite big to include...
You're looking for a block of non-prefetchable memory exactly 64K in size; this is from my card:
Memory at ff5f0000 (32-bit, non-prefetchable) [size=64K]
I forgot to comment out the bogus register_write in that code, so anyone who wants to use it, first comment out the register_write.
