The best thing would be to look at the log file for X (on Squeeze LTS
that is to be found at the following location: '/var/log/Xorg.0.log') in
order to know which driver you're using (amongst other things--errors,
warnings, etc.).

For the driver the following grep ditty seems to work fine:

curty@einstein:~$ grep -B2 'Module class: X.Org Video Driver' /var/log/Xorg.0.log
(II) Module fglrx: vendor="FireGL - ATI Technologies Inc."
     compiled for 1.4.99.906, module version = 8.95.3
     Module class: X.Org Video Driver
