There have been a lot of fixes to NVD0+ since you filed this bug. Could you try 3.11-rc6 (or nouveau/master)? If it still shows issues, please supply a complete dmesg as well as your vbios (/sys/kernel/debug/dri/0/vbios.rom).

I almost forgot about this bug. I use novueau kernel daily (with Airlie's auto-off patches) and the dmesg output looks OK with the recent version (3.11-rc6+).
