Ah yes, this needs to be fixed in some way.
Better of course to get the siginfo complete.

I just found another problem with this stuff: A little
test program trying to execute an illegal FPU instruction
panics the box. "kernel used FPU".
The panic is pmax specific, but the reason might be in
shared mips code... need to understand what happens.

best regards
Matthias
