Perhaps your right I should try to track down the methods that glscene(open
source pascal/c opengl implementation) developers use. As for the driver, no, I
have used both the latest intel drivers for fedora. All other opengl apps I've
tested work perfectly. However regression testing has made a huge difference as
I now have it working again. It is a bit slower than when it randomly worked
under 0.9.52 but at least it works and really that's all I care to see.
Working. Forget the fluff it used to work.

Seems pretty generic to me when an open source library for c and pascal fails.
Did you actually try any of the demos or are you just shooting to kill? Just
kidding ;). I'm sure since I'm not a wine dev I miss all the juicey tidbits.
BTW most of these demos compile successfully under both wine/lazarus and
wine/delphi 6. The really strange thing to me is the randomness in 0.9.52 about
1 out of every 100 times everything was flawless ... the rest of the time
nothing at all. To me that shouts wine problem... and since it worked sometimes
shouldn't it just always work? 

Forgive my lack of windows knowledge I barely know anything about it since I
haven't used it in over 12 years.
