I don't have any experience with Radeon cards under Linux myself, but I
recall that a number of people on this list (and also debian-laptop)
have recently reported problems with ATI cards and Xorg 6.9. Looking at
"man radeon" it seems to me that your card should be supported with 2D
and 3D acceleration. To isolate the problem, you could try to disable
the "AGPMode", "EnablePageFlip" and "AGPFastWrite" options in your
xorg.conf and also comment out the GLcore and the speedo module (they
are not loaded anyway). I would also reduce the DefaultDepth to 16 and
see if that changes anything. After you start X again, post all messages
in the log related to the card, i.e. run

grep "RADEON(0)" /var/log/Xorg.0.log

Hopefully somebody else will know enough to suggest further steps based
on that output.

I'd rather not try this. The only French I know is related to food, and
in the recent past many people have reacted badly to posts involving
edible items (melon, ananas, broccoli ou spam).
