   Yes it definitely will.  I haven't really done any optimisation.  I guess 
you don't have overlay support working though.  What does xdpyinfo say for 
your computer?  Also, can you look at the qtvision console output and see if 
you notice anything about finding an RGB??? display?

    You really should run Makefile.cvs, configure, clean, etc for this.  Too 
many big things have changed.  It's very likely that you are even running 
with a slower than possible input or output method.
