945GM/I810 OpenGL issue

I have two laptops with Intel 945GM gfx, both running CentOS 5. The Xorg
log reports build ID xorg-x11-server 1.1.1-48.13.el5. Kernel 2.6.18-8. I
also tested this on Ubuntu Gutsy, with the same result.
The problem: If I define a polygon stipple with horizontal or vertical,
one pixel wide stripes, my test app runs at ~300FPS. If I change this
stipple pattern to anything else, performance drops by a factor of 10.
I can provide test source code to demonstrate.
Apologies if this is the wrong forum.
