Since a while, wine is no longer able to initialize OpenGL on my 64bit Linux. This is by no means a unique problem to me- Lots of people with nvidia cards running 64bit linux seem to have this problem with wine on oneiric:

• http://forum.winehq.org/viewtopic.php?p=66856&sid=9d6e5ad628ee6fb6e5ef04577275daed
• http://forum.pinguyos.com/Thread-Wine-OpenGl-Problem
• https://bbs.archlinux.org/viewtopic.php?id=137696

And while some launchpad bug reports say one should use this workaround:

LD_PRELOAD=/usr/lib32/nvidia-current/libGL.so.1 wine <app>

It unfortunately does not solve the problem at all for me; That is, if i'd run CS:S, the game will run just fine for a while, but will abort after some time, including a range of GLSL-related errors.

Here the startup errors from simply running steam:

Here are the errors reported while running, and after running (because the log is huge-ish, it's pasted elsewhere): http://paste.ubuntu.com/901925/

Now, 32bit OpenGL works just fine; The 32bit executables of Nexuiz, for example, work just fine. That being said, I'm suspecting that this is a problem of wine itself.

I've already manually built the git version of wine, to no avail.

So what's going on? Is something broken? How do I check (correctly) whether something is broken? How do I solve this?
