[Bug 19406] Blank Screen, X freeze on my notebook ( Ati Mobility 9600 with radeon driver), ONLY with X.Org 7.4

Here goes my Xorg log and lspci -vn output.
About the DRI mode, that's what was set by default with Debian lenny, I didn't touch it.
After a quick peek at Xorg radeon module website, i added the following to my Device section:
Option "EnablePageFlip" "1"
Option "ColorTiling" "1"
Now i'm getting excellent performance and perfect stability, using XAA and AGPMode set to 1. The level of performance is the same i got using fglrx v8.37 back when i had openSUSE 10.3 with Xorg 7.2.
I tried the EXA settings, but the performance improvement over XAA with the above settings is only a few percent, at the expense of 100% cpu use (vs 70% with the XAA)!
