nouvea bug - how do I figure out if testing has the right patch ?

[<briand@aracnet.com>]

Hi,

I'm experiencing VT switching flakiness with the debian stable nouveau driver.

ii  xserver-xorg-video-nouveau                      1:0.0.15+git20100329+7858345

The symptom is that trying to switch a VT between x-sessions running on different
displays, i.e. :0 (VT-7) and :1 (VT-8) kills keyboard input.  The box doesn't lock, I can ssh in and reboot, but it does have to be rebooted.

I get a bunch of :

  syslog.0:Jul  9 23:15:50 windy kernel: [105281.262178] [drm] nouveau 0000:03:00.0: no space while hiding cursor
  syslog.0:Jul  9 23:15:50 windy kernel: [105281.426794] [drm] nouveau 0000:03:00.0: no space while hiding cursor

It _appears_ that this problem has been patched

  Fixed by xf86-video-nouveau commit 8378443bd3b26b57ef2ae424a700e01ead813d33.

Unfortunately it looks like the patch was committed in may, but even the unstable version 

  1:0.0.16+git20110411+8378443-1+b1: amd64 armel armhf i386 ...

may not include it (says 4-11).

How can I figure out if which debian version, if any, has the patch ?

Is it reasonable for me to try and build the latest version, should I not be able to get a debian package which includes it ?  Last time I tried to build an X driver it didn't end well, dependency hell and all that.

Thank you,

Brian
