Description

Hello


I'm trying to enable EXA acceleration on my FireGL v5600 by following the
directives written on the wiki (http://wiki.x.org/wiki/radeon%3Ar6xx_r7xx_branch).
Alas, it's freezing my system: I can only use my sysrecue key to reboot.

My lspci:
60:00.0 VGA compatible controller: ATI Technologies Inc RV630GL [FireGL v5600]

uname -a :
Linux brew 2.6.29-rc8 #1 SMP Wed Mar 18 08:34:15 CET 2009 x86_64 GNU/Linux
