I think it's not working yet. It seems to crash during starting the first 
thread. I traced the calls to here:

0x0040d45c: SYS_StartNextThread?
0x0041f6e8: ?

Raise exception at 0041cbe0 => 00000006 (21)

This seems to be due to uninitialised/incorrect data but without knowing 
what the data structures are it is hard to tell.
