I don't believe any work is being done on userspace drivers. If you want to
look specifically mach user space drivers you can read the mach 3 Kernel
Interface[1]. If you aren't specifically looking at mach drivers, perhaps
you may want to acquint yourself with oskit, and how GNU Mach in cvs uses
the interfaces in oskit.
