Hello.

I am trying to use the nouveau driver in an Aspire 9420, which is shipped with
a go7300 nvidia card. The lspci line is this:

01:00.0 VGA compatible controller: NVIDIA Corporation G72M [Quadro NVS
110M/GeForce Go 7300] (rev a1)

I am using the following software:
* gentoo x86_64
* kernel 3.17.1 from kernel.org, no patches
* no fb driver enabled, other than what the nouveau drm stack enables
automatically as deps
* no compositor, no xorg.conf
* libdrm, xf86-video-nouveau and mesa from git as of today (oct 25, 2014)
* xorg-server 1.16.1

When I boot my machine I can see the fb coming up, and the mode is set ok (with
tiny characters and such). When startx takes into scene, then the screen
becomes a pile of garbage. The laptop is not hard-frozen however. Most times,
after like a minute or two I am taken back to the console (not always though).
In any case, the computer is responsive. I can control+alt+del it even when the
console remains garbled. Because of this, I was able to easily save the X log
and the dmesg output, which I attach along with a photo of the corrupted
screen.

I have tried rebuilding everything many times, in the hope that any ABI issues
went away, but no change.
