Good luck.

I have a similar problem with my Sony + ATI graphics.  After trying every
think I could think of (and google) I found a page that said that my
lappie didn't have enough video memory.  When I looked I found this is
the XFree86 log (Xorg hasn't been forked from XF86 for that log to be
that difference):
   (II) RADEON(0): Memory manager initialized to (0,0) (1408,1489)
   (II) RADEON(0): Reserved area from (0,1050) to (1408,1052)
   (II) RADEON(0): Largest offscreen area available: 1408 x 437
   ...
   (II) RADEON(0): Acceleration enabled
   (==) RADEON(0): Backing store disabled
   (==) RADEON(0): Silken mouse enabled
   (II) RADEON(0): Using hardware cursor (scanline 1052)
   (II) RADEON(0): Largest offscreen area available: 1408 x 434
   (II) RADEON(0): Direct rendering disabled

3D (as I understand it) need loads of memory and they don't put enough
into laptops (which I can understand as more memory equals shorter
battery life).  I've just come to accept that I can't do 3D in hardware
on my laptop.

Good luck.
