Moving to the (two) nvidia-glx driver packages. This isn't (directly) going to be a problem with Xserver 1.5, because the nvidia drivers don't actually use any of the X server's GL stack (although it might be lack of optimisation against the new X server ABI or somesuch).
Further debugging at this point would probably be filing a bug report with nvidia on the nvnews forums(!). I don't think any part of this bug will be in anything we have source for.
