ATI card gives bad image via OpenGL

ATI Radeon HD 5670, driver 26jan2011 = 8.821.0.0.  Win7-x64

When I output via OpenGL glu32 the tesselation is horrible.  If I use our tesselation, then it is better but rectangular facets do not render.

Exact same app runs great on different Win7x64 computer using Intel built-in graphics.

Anyone know how to fix this?

Is there some way to turn off ATI tesselation?

I noticed another thread similar but different:
