In the past I've already played planetpenguin-racer (at that time it was
called tux-racer...) on the same hardware (and sempron 2800, 1Go Ram,
ATI aiw radeon 7500) and it was pretty playable.
But, few days ago I wanted to have a look at slune, and I found that it
was slow, that's why I think there is a problem with 3D hardware
accelaration.
And now I've just tried ppracer and get only 2 poor frame (with a
640x480 resolution) it's impossible to play.
Am I missing something ?

OK, that indeed suggests that there is something wrong with your
hardware acceleration. 1600 FPS for glxgears seems fine to me (I have
around 900 FPS), so we have to look somewhere else for the problem.
I agree, it looks very strange to me....
Please post the following sections from your xorg.conf: "Module",
"Device" with the graphics card in it, "Monitor", "Screen",
"ServerLayout", "DRI", and (if it exists) "Extensions". Also tell us
which version of the kernel you are using (run "uname -a").
Here are the requested informations:
I'va attached my xorg.conf
the kernel I'm using is one on the latest for unstable : 
uname -a
Linux debian 2.6.16-1-k7 #1 Mon Apr 3 13:11:57 UTC 2006 i686 GNU/Linux
Then (re)start X and look for errors and warnings in the log file:
egrep '^\((EE|WW)\)' /var/log/Xorg.0.log
Post all output of this command here.
I think you've hit the point (I hope that I'm using this _expression_ the right way) :
egrep '^\((EE|WW)\)' /var/log/Xorg.0.log
(WW) The directory "/usr/lib/X11/fonts/cyrillic" does not exist.
(WW) The directory "/usr/lib/X11/fonts/CID" does not exist.

(WW) Open ACPI failed (/proc/acpi/event) (Device or resource busy)
(WW) Open ACPI failed (/proc/acpi/event) (Device or resource busy)
I've made a big mistake, last time I check X log I've looked at XFree86.0.log... You known, the old one... I'm dumb...
Now the good question is why DRI isn't running ???
Do you have any idea ?
Start ppracer from a terminal, exit it again and check if you got any
error messages. Also have a look for anything graphics-related in
.xsession-errors. Hopefully something will give us a clue where things
go wrong.

P.S. Your English is fine (and certainly better than my French).
thank you ;-)
lets give your French a try !!

Thanks again !!!
