Disabling shader blocks in G9X/G8X?

[Freak'n Big Panda]

I'm trying to mock some mobile Geforces for comparison purposes and I was wondering if there was a utility that would allow me to disable some of the thread processing clusters to change my 9800 GT (7 clusters) into a 9800M GT (6 clusters)?

Rivatuner used to let you do this back in the day with NV40. Not sure if it still works on newer chips.

I'm not seeing an option using Riva Tuner 2.2.2 and the latest NV drivers. Anybody have any other suggestions?

Maybe the NV bios editor can do it? NVbiditor or whatever it is called?

wizzard from tpu used something to disable shaders on a 4850 "on the fly" when he reviewed the 4830 with missing shaders.

Well thanks for the suggestions guys but it seems this is no longer possible. It *was* possible with rivatuner using earlier drivers but NV has since patched that hole so it's no longer possible.
