Should've read the error message in context shouldn't I?

In /etc/X11/xorg.conf there is the following lines:
...
Section "Extensions"
       Option "Composite" "Enable"
EndSection

Comment out this entire section (need to be root/sudo) then restart the X 
server and voila.  Accelerated 3D again.

It seems the composite extension is incompatible with the 3D acceleration.  No 
big deal for me, I don't use it.  If you have turned on experimental 
transparencies etc, then this conflict may affect you too.  The fix is to 
disable the composite extension.

HTH someone out there....it's been bugging me for a week or so :(

Cheers,

James
