I need to write a real simple device driver to access a device on the 
Sbus (it's a proprietary card.)  I can probably get the interface 
documents for the card (but can't share them :) so my next hurdle is 
how to talk directly to the Sbus.

This code is more of a "prove NetBSD can be used to talk to this type 
of Sbus card" rather than a "production" piece of code, although; the 
better the code looks, the better NetBSD will look.

Any help would be greatly appreciated as the alternative is buying 
SunOS/Solaris (for which drivers already exist).

I've done device driver development in OS-9/OS-9000 so I have a clue 
as to what needs doing, I just don't know how to do it the "NetBSD 
(a.k.a. correct)" way. :)
