I've had such a driver before. Trust me, it was a great relief once I got rid 
of it because I did not have to maintain the os abstraction layer anymore. And 
many of the lower level functions you need to do by hand for all systems can 
be done with fewer calls on nearly all systems. Just the borders of these 
calls differ between the systems, so you can't abstract this away in the 
wrapper layer.

And noone stops you to have your driver available for older kernel releases 
too. But plugging something in and it just works is just cool ;)
