That actually sounds like really fun!  haha.  I bet it would involve
diving into the mach code...I believe that the Hurd currently uses
drivers from linux via DDE.  A lot of that code was shoved into
GNU/Mach.  You'd have to pull it out, or find the commandline option to
not compile it in...but I don't know how to do it.
