I'd like to add that I have experienced the same problem with Fedora 15 and
Ubuntu Natty with the same hardware. 

Also, I have a newer laptop with NV34 chipset, the above distributions and
Gentoo works perfectly on that.

Just been doing some additional work on this. Apparently disabling LVDS-1 got X
working.

I am now building 2.6.37 and testing again to see if the fixes applied to that
kernel solves the issue entirely.

Ok, 2.6.37 is a total disaster. 

Booting w/o video=LVDS-1:d resulted in a solid kernel lockup. Not able to ssh
in and look for myself what was wrong.

Booting /w video=LVDS-1:d, resulted in a booting 2.6.37 kernel, looks OK but X
wouldn't start.

Makes no real difference,the problem is with X trying to start up but not
getting what it needs. Console working perfectly OK. 

2.6.37 could not even boot with all vga/video related parameters removed,
needed just LVDS-1:-d to even boot. 

I suspect something has substantially changed for the worse with 2.6.37.

I added a xorg.conf to the 2.6.37 kernel, and got a GPU hang. Eep!

Added xorg,conf and relevant logs.

index cfb8a3c..97de9e1 100644 (nv10_invalid_placement_range.patch), and same
kernel parameter arguments, it boots just fine but X still exhibits problem.
New logs added. 

Next thing to do is to test kernel without these parameters.

Here's some extra information.

Apparently if I add 'video=LVDS:d' to the kernel parameter line, the
hang with
2.6.37 doesn't happen. This definitely was not needed with 2.6.36.

Some more experiments w/ the video=LVDS-1:d parameter on 2.6.36

Without creates a 1600x1200 display but console thinks it is 1024x768
With it creates a 1600x1200 display and console thinks it is 1600x1200. 

I hope this is of use!

The attached patch should help with that crash. To find out why we can't
find a
native mode for your LVDS panel, can you get me a BIOS dump? (see [1])

This patch is also required to prevent X crashes.

Thank you, the two patches given above fixed the problem entirely for me, no
more X or kernel hangs with 2.6.37. I now consider this report closed. Until
the next time :)

This should be fixed in nouveau/master now, marking as resolved.
