System is a Pentium II with a Diamond Viper V550 (Riva TNT) card. OS is Arch Linux, with latest versions of Nouveau from git repositories on freedesktop.org:

kernel 2.6.34-rc5 libdrm 2.4.20 xf86-video-nouveau 0.0.16

I have "options drm debug=1" in /etc/modprobe.d/modprobe.conf. Acceleration is enabled.

With this setup, X works for a few minutes and then crashes. I was running Firefox and lxterminal (am using lxde with openbox window manager). The first problem I saw was the titlebar for lxterminal was not always rendered. Grabbed the graphics from the web page behind it. The crash happened when I tried to search for something in Firefox's search dialog at the upper left. Went into a loop in which the pop up menu of suggested search terms flickered on and off perhaps 10 times, then X crashed. Saw many of these messages in kernel.log:
