Having helped NTFS (and probably FUSE) to get going is one of the UML
merits, but we likely should advertise this (we know this indirectly,
by having seen those projects' authors using UML for debug).

Start posting some of these errors and we'll look at how trivial it
is (unless the compiler is flooding you). If they look trivial to us
we may try it...

But my 1st question is: does OpenMosix currently support anything
else than x86? If not a little compatibility layer may be needed and
this may hinder significantly the porting - however they'll have to
fix this anyway to support x86_64 at the very least.
