Nouveau/X server crash + backtrace with Randr12

DFP is a Sharp LC-42D64U 1920x1080 LCD HDTV connected via a DVI->HDMI cable.

nouveau incorrectly detects this panel as 1320x768 and ignores the 1920x1080
modeline, then starts properly at 1360 x 768. Unfortunately this is not the
native resolution of this panel and it looks terrible.

After reading some other bug reports here it was suggested adding option
"Randr12" may resolve the problem. This causes the X server to crash
with a
backtrace (see attachment)

Its also interesting to note that the NV driver gives this message in regards
to this panel:

(--) NV(0): Panel size is 1360 x 768
(II) NV(0): NOTE: This driver cannot reconfigure the BIOS-programmed size.
(II) NV(0): These dimensions will be used as the panel size for mode
validation.

and refuses to set 1920x1080 as well.

I will attach all the Xorg logs from nouveau as well as an EDID dump from the
display.

Never file bugs against older driver revisions, i suggest you at least update
to the latest version and try again.

I attempted to build the latest version and ran into compile issues with the x
driver. I think I may know the reason though and I will build it again and
recreate the bug report if required.
