Slow frame rate in X while running 10.2-BETA1 r285410M

[Leonard Rucker]

Hi Jean-Sébastien

Sorry for the delay.  Between work vacation and more work, I didn't see
this message until now. I have always loaded the Radeon drivers on boot but
I didn't try not loading it on boot.  I'll try that.

I actually tried buying a new AMD motherboard and CPU to see if there was
some sort of problem with the current one I was using and there was no
improvement. Acutally since I went from a 3 year old  A8 to an A6 processor
the computer seems slower and I sound over hdmi no longer works,  But at
least I am reasonably certain that something else has changed with the OS.

Thnaks
