VGA Arbiter
After upgrading Xorg from 1.6.5 to 1.7.5 I can't use my quad head Quadro NVS 440 anymore. My Xorg log contains:

(WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
(EE) Aug 06 17:42:49 NVIDIA(2): Failed to initialize the NVIDIA graphics device!
(EE) Aug 06 17:42:49 NVIDIA(GPU-1): Failed to initialize the NVIDIA graphics device!

Is this a problem with the nvidia-driver (I'm using 195.36.15) or with the new Xorg?

Re: VGA Arbiter
Please generate an nvidia-bug-report.log file after such a failure and attach it.

Sorry for the delay. Here is the nvidia-bug-report.log for that system. The behavior is that the third monitor (Screen 2) never shows up and never comes out of power save mode. The first monitor (Screen 0) works fine. The second monitor (Screen 1) comes out of power save, but as soon as I move the mouse over to that screen the X server locks up.

And, for reference, here is a nvidia-bug-report.log for my working FreeBSD 8.0 system. It is using the same hardware, I installed 8.1 to a new disk so I can fairly easily swap between them.

Re: VGA Arbiter
Can I politely ask if anyone has looked at this?

I upgraded my nvidia-driver to the 256.53 port and then tried things again. I still cannot get the second GPU on my Quadro 440 to work. Attached is a nvidia-bug-report for my latest attempt.

Any help would be appreciated. Thanks.
