dmesg of nouveau module load and startx

My NV4b card starts X but it results in a black screen.
I see a bunch of errors continually like:
[drm:drm_edid_block_valid] *ERROR* Raw EDID:
...
nouveau 0000:03:00.0: TV-1: EDID block 0 invalid.
[drm] nouveau 0000:03:00.0: DDC responded, but no EDID for TV-1

I am connecting the card to a vga display via a dvi+vga converter.  
I tried disabling tv out by using tv_disable=1 at the command line but that doesn't seem to help.

This card has actually started X fine in the past and this is the same monitor I used before.

I am running the latest nouveau-linux-2.6 kernel (764e0885f987171030368a3f20993cd2855c4e40).

Uhm, I'd swear I had fixed this a couple of weeks ago... It seems the merge of "v2.6.36-rc1" reverted half of the fix by accident, can you try again with latest git?

Yes, it works fine now.
