Here are a few updates as to what has been going on with my attempt at getting the OpenGL/Xpress 200m issue resolved.
1) It is my theory that it is a Video Firmware Issue. I am still awaiting some confirmation as to my findings, but most people I have submitted my test data to are in agreement.
2) HP, for the most part, is ignoring my repeated trouble ticket submissions.
Here are the driver sets that I’ve used:
ATI Catalyst 5.5 through 6.1, when ATI dropped Xpress 200m support
HP driver for zv6000, old and new — new being 11/2005
Catalyst 6.8 drivers (ATI re-added support for the Xpress 200m with this release)
