The X server seems to be loading the NOUVEAU driver properly (based on the contents of Xorg.0.log), but I have one X11 application that doesn't work correctly; it runs as though XSynchronized is always True, even though it's explicitly set to False in the code. In other words, its redraw behavior is god-awful; worse because it auto-redraws once per second for little apparent reason.  And some of the windows draw with artifacts if they're covered and uncovered.

This is definitely new behavior on this new computer (the previous computers, also using the Nouveau driver with GeForce 7600 cards, did not seem to have this behavior).

If you just want an easy solution you could try the nvidia drivers from 
elrepo. Start with nvidia-detect to find out which version you need, as 
explained here:
http://elrepo.org/tiki/kmod-nvidia

If you actually want to debug nouveau or whatnot, that's another matter.
