Just a side-note on this bug: I get this very same output like you in Doom3 retail:

trace:wgl:dump_PIXELFORMATDESCRIPTOR   - dwFlags : PFD_DOUBLEBUFFER
PFD_DRAW_TO_WINDOW PFD_STEREO PFD_SUPPORT_OPENGL 
trace:wgl:X11DRV_ChoosePixelFormat No matching mode was found returning 0
trace:wgl:X11DRV_DescribePixelFormat (0x17c1218,0,0,(nil))
err:wgl:ConvertPixelFormatWGLtoGLX invalid iPixelFormat 0

See http://bugs.winehq.org/show_bug.cgi?id=7015 to see that there is a bug in
wine's code how it handles the PFD_STEREO stereo flag. I dunno if this the
problem here too however. For now i use following stupid hack below to start
Doom3, maybe it changes something in your app too
