UMSDOS is broken in 2.4 in few places.

You can try to change link sequence by placing
in fs/Makefile.

Then you'll get UMSDOS being registered, and possibly an oops

As I remember, the pseudo-root feature doesn't work
(Certainly it did not work in test7 and I did not notice any patch for
it since that time)

Seems that it is unmaintained at the moment...
