I wouldn't expect either of the existing 8255 card drivers to work "out 
of the box" with that card.
Measurement Computing has published the register specs for the card, so 
it should be pretty easy to write a driver for it or modify the AX5214 
or PCI8255 drivers.

Note that the Mesa Electronics 5I22 PCI FPGA card is about 2x the price, 
but has 3x the I/O, and also has an FPGA on it that can provide high 
speed PWM, quadrature encoder counters, plain I/O, etc.  The FPGA cards 
have another advantage as well - a single access will read or write 24 
I/Os at once.  The 8255 needs 3 reads/writes, since it has 3 8-bit 
registers (so it won't allow quite as fast software step generation, for 
example).
