Has anyone inquired about this on the mosix mailing list ? And if so,
is there a  way to fix it ? Cause, I would then like to run a mosix kernel
all the time, instead of only after working hours.

MPI programs won't work, as mosix doesn't yet implement migratable sockets.
I hear that the mosix guys are researching on this.

PVM should work though, cause there are some MOSIX/PVM papers available from
mosix.org. Of course, they couldn't have measured performance if it wasn't
possible. ;-)
