Thanks;

I am earlier in the process with OpenBSD.

But this would be useful to me. It is much quicker for me to compile
load test unload a driver under development than to
compile reboot test.

So what are the issues ?
And any pointers where I might look to try to fix them ?

Ignoring robustness, can I roughly follow the char device module
skeleton, add the pcmcia/cardbus hooks compile and load something
and expect that if it does not work it is because something is broken,
or is there functionality that is missing ?

If you could provide a starting point I would be happy to see what I
can do concurrent with trying to get my own driver working.
