Xgl won't start

I installed Xgl from Debian GNU/linux xgl Packages , and it worked. However, it was a bit slow, so I decided to install DRI accleration for my mach64 ATI 3D Rage Pro, using the drivers from dri.freedesktop.org. After that, plain Xorg starts and works, but Xgl fails with "No Screens Found".

Attached files:
Program: filename on system: Attached file name
Xgl's log: /var/log/Xorg.93.log: Xorg.93.log
Xorg's log: /var/log/Xorg.0.log: Xorg.0.log
Xorg.conf: /etc/X11/xorg.conf: xorg.conf.txt
Script used to install dri: ~/3daccel.sh: 3daccel.sh.txt

Note: the two logs are zipped together in logs.zip
