Ok, I managed to catch up. So let's see:

1. You do have client GLX 1.3, but server GLX 1.2
   Raphael: That amounts to GLX version 1.2, the lower version is
   important.
2. You have a different problem. The calls to glXChooseFBConfig return
   NULL because your card doesn't want to do the requested visual. If
   you look closely, you will see another call to glXChooseFBConfig that
   does not fail because your card wants to do this visual.
3. bug #3956 should be closed.

Hi,thanks for looking into this. Appearantly this bug
is different from the ones you're writing the patch
for. I found that when i run it like this:
WINEDEBUG=+relay,seh wine doom3.exe 2>/dev/null 
the app comes up just fine. Somehow it needs to be
slowed down a bit. I'll do some more digging to see if
i can find anything useful. The bug must not be
closed, as doom3 _does_ crash when i run it with
current cvs in  a normal way.

Hi,

can you try to provide a 
WINEDEBUG=+tid,+opengl,seh wine doom3.exe
log ?

seems a race problem
