Writing glue code for getting a bunch of drivers is less work for more
result than writing native drivers.  Yes, driver interfaces change, but
not that frequently.  The problem here is just that nobody took the time
to update the glue code, probably because this needs both gnumach and
linux knowledge.

Another solution is Xen.  Porting GNU mach to Xen and writing Xen native
drivers shouldn't be too hard, and should be relatively stable.  Of
course, this doesn't permit to run GNU mach natively on machines, but it
permits a much broader support for people who might want to try the Hurd
(note that more and more Linux distributions include Xen packages).
