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]
