Unfortuately you have an older version of the card that is I/O-mapped
only, and I never implemented support for these. It should be easy
though.
Please find attached a diff that ought to work. Note that I haven't
fixed the resource accounting, so attempting to unload or shutdown might
result in a trap.
If that's the case, comment out the code in mlx_free() that releases the
register window mapping. You won't be able to unload and then reload the
module, but you'll be fine otherwise.
Let me know how you go...

... every activity meets with opposition, everyone who acts has his
rivals and unfortunately opponents also. But not because people want
to be opponents, rather because the tasks and relationships force
people to take different points of view. [Dr. Fritz Todt]
