	Ty, ty, ty!  For unknown reasons (I don't know how I screwed up
	and set this:-), I also set the screen to require my passwd to
	bring it back to life.  But that's another issue; it'll be awhile
	before I figure out the widgets and gimmicks of Gnome/KDE.  
	You've givenme a jump.

	Will Gnome choke if I put the ``xset [foobar]'' string  in ~/.gnome2?
	I want to add some initiation commands for the window manager and
	the gnome-[stuff] seems to choke if I make the slightest fumble.

	Hm...  Well, I'll experiment.  One at a time; blanktime=NO 
	or xset s off.

	Wow, that is very close to my problems:: with my G450 and 
	the mga-1.9.100, my screen was only bright at 800x600.  My
	workaround,, suggested by a gent in OZ was to use xgamma.
	xgamma -gamma 0.100 only works up to 1280x1024; but I've got 
	32megs on this video card, which is plenty.  I haven't written a
	dev driver in years.  The patch code looks interesting.  

	I didn't understand that I could file a PR thru FBSD for an
	xorg driver fault... .
