Excerpt from the "DRI User Guide", concerning the G450
( http://dri.sourceforge.net/doc/DRIuserguide.html ):
"It should be noted that currently the second head does not 
support direct rendering."

The second monitor should be used for your PD patch and the 
first for GEM.  But you can't use Xinerama since it would
disable DRI on both monitors.  So the X desktop should run 
on the second monitor and GEM should open it's screen on the 
first monitor which support DRI.  But how?
