Stable if someone has too much time ;o)

The Problem is, that MiNT does not make taskswitching in supervisor mode.
The filesystems for MiNT have to be fixed, as they rely on this fact, as
far as I remember. So you have to fix the filesystems and to that, you
have to take an eye on Bios and Xbios. I bet, they will make some
problems, too. But for Bios and Xbios don't exists free avaiable sources,
so they have to be written from scratch (and should be in Assembler, of
course :o)
