It works here (e.g. programs/demo/flying_ggis with GGI_DISPLAY=palemu,
on an XGGI running in 16 bit mode).  programs/demo/demo mostly works
too, but I've noticed it hangs sometimes.  Here's the back trace after I
kill -11 it:

I don't see the hang on the console.  Marcus, could that be a bug in the
GII X input driver, or something else ?  [maybe just my crumbling libc5
system ? :-))]

Cheers,
