[ltp] Proper setup of Quadro NVS 140M with t61

[Micha Feigin]

I'm trying to find out the proper setup of my graphic card with X11 for the
T61, graphic card Quadro NVS 140M. System is debian unstable with the nvidia
beta driver.

I have a constant feeling that I'm not configuring it right, glxgears is very
inconsistent in performance, going from 1000fps to 6000fps on different
start-ups (not sure yet if changed settings). Compiz feels very slugish
(zooming out the cube is ridiculously slow). Some of the 3d games seem ok, but
I still feel that this card should give me more.
Also 3D takes a lot of cpu, seeming to me to suggest that something is not
using the gpu properly.  glxgears fires one one the cores to 100% (cpu shows
100% under top with cpu scaled to 2ghz and x running at 15%). cairo clock causes
X to go to 30% cpu under top.

Anyway, the relevent parts (I think) of my xorg.conf, anything strike anyone
here as wrong, too much or something missing?

by the way, nvidia-settings claims I have 512mb which I don't think this card
can come with, but maybe I'm wrong,

 thanks
