Dear nouveau hackers,
I got as far as figuring out that Xinerama is deprecated now... Too bad
WindowMaker doesn't play well with RandR. While painfully learning about
it, I managed to crash my Xorg 1.5.3 server through the nouveau driver.
The attached patch fixes it.
To reproduce the crash, simply run X with Xinerama enabled.
$ gdb hw/xfree86/Xorg Xorg.core
[...]
Core was generated by `Xorg'.
Program terminated with signal 6, Aborted.
