Reference counting is a big thing.  wrstuden@netbsd.org did a bunch of
this stuff for network drivers, and it's waiting to be cleaned up and
integrated...

Then you have to deal with "what do you do if a user just rips the card
out" w/ serial devices, etc... and waiting for detachments from interrupt
context, etc.  It's a hairy issue, actually.
