I've never heard of an Ironics, but I agree the best way to handle
these types of boards is with a /dev/mem-like device.  For example,
I wrote software for a Datacube MinVideo board to provide a read/write/
lseek interface for the large transfers (writing the display buffers
and colormaps) and a ioctl based interface for poking individual bytes
in the scads of control registers for the board.  It took about a
days worth of editing to modify all their libraries that used phys
to use this interface (I even found a few bugs in the process).
