DRI on Ati 9100 IGP

[d80tb7]

Helleo everybody.

First let me say that I'm a Linux newbie so bear with me

I've recently installed FC5 and have been very impressed with it: the only problem left for me to solve is how to get harware acceleration working with my Ati 9100 IGP. This isn't supported in the official Ati drivers but I believe it is with the open source "radeon" driver supplied wth Fedora (at least that what the output form the 'man radeon' command seems to suggest).

Anyway, I made what I though was an appropriate xorg.conf file and started x. Everything is good and /var/log/Xorg.0.log looks fine with lots of lines like:

DRI installation complete

and only one thing that looks like an error which is:

(EE) RADEON(0) : drm: could not allocate surface for front buffer

A google search shows up very litte of interest fro this error.

Anyway. To check if dri is working, I use the command
# glxinfo | grep -i "direct rendering"

which returns
direct rendering "no"

glxgears returns ~150 fps which I believe is not good either.

I wonder if anyone here knows what I might be doing wrong or even if dri is supported for my card. I've enclosed my xorg.conf (i tried to add my Xorg.0.log but it was too long) below. All help is, of course, much appreciated.
