backtrace of crash w/ exaPrepareAccessReg_mixed()

Whenever when I start a wine application (the best example I have is
Notepad++), X crashes either by locking up or restarting itself.  I can
reproduce it every time with Notepad++ (one of the only wine apps I even have).
Sometimes I can reproduce it with the standard Notepad as well.

I'm using a 9500GT with xserver-xorg-video-nouveau package
0.0.16+git20110323.8378443b-0ubuntu0sarvatt on Ubuntu. (xorg-edgers ppa)

I have collected some data, which I've attached, from another computer via ssh
and gdb.
