Ah, ok. I see the problem. Basically this has to do with the fact that choosing the hw vertex format has gone from being something (normally) done ahead of time, prior to actually running the tnl pipeline, to something done after that, and based on its results. The only problem is that by this time, the pipeline has run, and it's too late to decide whether or not to calculate projected coordinates. Oh well, it's not too hard to do that ahead of time.
Here's an updated patch. In addition to the above, I've fixed up the way 'coloroffset' and the previously hardwired 'specoffset' are initialized. Most stuff seems to work ok now, except tuxracer-demo, which has issues which are probably related to polygon offset.
Right now both your latest patch and my patch seem to be totally hosed. I haven't changed any of my code since Friday (when it mostly worked), but there have been some changes since then in Mesa. Anything that uses textures has major issues with my patch, but things that don't use textures seem to (still) be mostly okay.
Can someone verify that other drivers that use t_vertex still work okay with current Mesa?
