It doesn't succeed. I added some FIXMEs to the code to get output for 
debugging and this is what it printed before it crashed:
 >fixme:wgl:X11DRV_WineGL_InitOpenglInfo pglXMakeCurrent returned 0

I know it's not going to make it work, but it's still a good idea to 
have descriptive error messages. It helps less technically skilled 
people figure out what's wrong. Also wine-devel isn't really the place 
to ask for help setting up 32-bit drivers, so I didn't ask for that help 
here. If you want to help me we should email each other outside of the 
mailing list.
