I hate to reply to myself but I did try one more thing that worked.

My Radeon 9600 Pro has a VGA port, a DVI port, and an S-Video port. I had
been using the card on an analog CRT but it was plugged into the DVI port
using a DVI->VGA adapter. I don't remember why I did this originally, but it
had been working.

I moved the monitor to the VGA port, rebooted, and ALL of the problems went
away. No color ghosting/bleeding, no large fonts, and glxgears is getting
~1500fps. There were several posts stating that problems came and went when
various connectors were used (or not used). It appears the current driver
has some (connectortable?) issues.

Now to try compiz again after backing out all the changes...
