Where `one point' == `last night' :-)

I'm not quite sure about the way I've done it -- I might set it up to
always claim rather than only claim on device detection, and take the
name from the hardware database rather than the driver.

I suspect I've broken module unload with the current code, and I need
a release_mem_region on deregistration... investigating now.
