I'm still trying to figure out how to get the XDRIVER to handle 'Expose'
events properly.  Unfortunately, I know little about X programming, and
am unsure what the XDRIVER would use to repaint the screen (if the
server won't do it with backing-store).  Note:  I'm running KDE2.1beta
and this problem doesn't exist here (with the changes to XF86Config to
always do backing store).

Yea, I'll try to clean up some of the reporting/d.mon stuff.  My first
goal was just to get it working ;)
