I remember working on this a couple months ago.  I put the driver
detection in winmm.c, but that was wrong.  I can't remember exactly
what I was supposed to do to fix it...something like put the driver
detection in each driver.  I'm not really sure what that means or how
it would work if it does what I think it does.  Does it mean that we
load one driver, and if it doesn't detect its *nix counterpart then it
loads the next driver?  I would like to get to work on this task, so
if anyone has any pointers or ideas on this one, please let me know.
