From Debian Sequeeze on, the KMS is enabled by default. But the ATI card is not compatible with the KMS.
When the KMS enabled, the score of glxgears is around 40 FPS on my laptop which has a ATI Radeon X300.
The worst thing is the system becomes unstable, the screen could be frozen at anytime.
Disable the KMS by the way of /etc/modprobe.d/radeon-kms.conf.
Update this file with command:
echo 'options radeon modeset=0' > /etc/modprobe.d/radeon-kms.conf
Then reboot the system.
Now the score of glxgears gets back to around 1700 FPS.
