Yes of course, I didn't take into account the vga module patch.

No, the whole code is reentrant I think, since it works under DOS. The
problem is related to I/O privilege levels: the timer thread hasn't got
enough privileges to do raw I/O call.
It looks like threads created with the POSIX pthread_create() call don't
inherit I/O privileges from their parent process. Yet quoted from the iopl()
man page: "Permissions are inherited by fork and exec."
If you comment out line 180 in src/linux/lsystem.c and put an 'iopl(3)' call
line 70 in src/unix/uptimer.c, all works nicely (that's of course not a
recommended fix ;-)
