Ok maybe my comment above that
in /etc/default/acpi-support as given abave by jkyamog is the solution, needs to be corrected:

Now when i do
$ fglrxinfo I see:

Xlib: extension "XFree86-DRI" missing on display ":0.0".
display: :0.0 screen: 0
OpenGL vendor string: Mesa project:
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.4 (2.1 Mesa 7.0.1)

ie i am using the mesa open-source driver ...
and lsmod does not show the fglrx driver anymore -

I believe before i added those two lines in /etc/default/acpi-support , i saw fglrx in lsmod listing.
