Oh great.  And here I thought that I was behind and I'm actually ahead
of the curve?  Uh oh.

I wonder what the difference is?  Do you have the 1920x1200 display,
or the 1680x1050?  I have the 1680x1050 screen.

I may have to try that.  Strangely, fglrx works fine for me except
that I have to manually convert screen resolutions after logging in.
glxgears reports 1229 FPS.

There isn't much in my xorg.conf, but you are welcome to it.  Maybe
together we can get full resolution
