That is right. I was using the "driconf" utility to set the configuration, 
which in turn uses xdriinfo, but that reports the driver to be "r600", not 
"dri2". So I changed the driver name in the ~/.drirc from "r600" to "dri2" and 
it started to work :-) Does the radeon driver have anything to do with the 
"driver name" as reported by xdriinfo?

Thanks,
Oldřich.
