The problem is most likely not
in dosemu itself (kernel? udev?)
Dosemu does what's the attached
simple test-case does, which
fails on FC3 too.

There are the already-written
CPU emulators. I was playing around
the qemu, which has the vm86()
syscall emulation. It was possible
to run dosemu entirely under the
qemu user-mode emulation, so it
was very promising. I almost got
it to work inside the dosemu, but
at some point its author abandonned
the user-mode support and dosemu
no longer runs under it, and so
I had to abandon my porting effors.
If/when (which is now unlikely)
qemu is fixed, I'll probably look
up that code and complete the work.
There are the other CPU emulators
too, but qemu have the ready-to-use
vm86() emulation, not just the CPU
emulation, so it is the primary
target of course.

Another interesting thing would be
to have the Windows port - someone
already built the dosemu with help
of coLinux, and it even worked.
