Hmm. This looks more like some strange viewport problem. No idea what
could be done about that, except you could try to start X with a 
slightly higher resolution (like 832x624 or so), but still play nwn at 
800x600. That's just a shot in the dark, though.

Theoretically, tcl_mode=0 should no longer be necessary with the new
driver snapshot.

That's a VERY steep performance hit for disabling TCL. It should not be
THAT bad afaik, it certainly isn't that bad for me.

No, there's no patch for fixing flicker problems with textures. These
patches have been long integrated into cvs and thus the snapshots. The
only patch around is for enabling s3tc and thus high-quality textures,
but this will not change flickering for sure.
I thought all the flickering errors were finally gone - apparently not 
(well they are gone for me on r200). Maybe it will get fixed one day, 
but don't expect it too soon :-(.
If you still don't have much video memory left, that could also possibly 
cause some errors maybe - not sure, I think you can't lower resolution 
even more for nwn just to try.
