Wow, and you can actually run X with the current fglrx driver?

I have exactly the same laptop and fglrx never worked here in Jaunty.
Every time I tried to start X it froze the whole machine ( and really
frozen, only hard booting possible after it)  if I wasn't fast enough
to switch to tty1 on start.
I chose to use the free radeon driver instead, which of course also
means a limited set of desktop effects with XRender, as OpenGL simply
refuses to work without freezing the X session. Reproducible every

I have found very few reports of people actually running OpenGL with
this card, but far too poor information is available on how to
actually tweak the system to make it work again as in Intrepid... so
some detailed information on which exact xorg.conf settings needed
would be very welcome!
