Finally got Maya to work, no more viewport update bugs!!
My setup: Intel Quad core, Nvidia 8600gt, 4gb ram, Windows XP 64.

Install 64bit 158.22 forceware drivers

Put MAYA_NO_VERTEX_ARRAY_SELECT = 1 in my maya env file.

Then in your nvidia control panel:

Threaded optimization = off
All the antialiasing and vsync stuff = off
Multi-display/mixed-GPU acceleration = single display
Horizontal Span (to get opengl to work on 2nd monitor)
