Output of dmesg

With nouveau on the graphics adapter on an HP dv2815nr laptop, both console and
X displays show an incorrect scan length with a resulting garbled screen.

The 'lspci -nnv' for this adapter is

00:12.0 VGA compatible controller [0300]: NVIDIA Corporation C67 [GeForce 7150M
/ nForce 630M] [10de:0531] (rev a2) (prog-if 00 [VGA controller])
        Subsystem: Hewlett-Packard Company Device [103c:30d6]
        Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 10
        Memory at f4000000 (32-bit, non-prefetchable) [size=16M]

        Capabilities: <access denied>
        Kernel modules: nouveau

This device has never worked with nouveau on any kernel. I am trying to make it
work now as the nv driver is failing in certain cases, and fbdev cannot use the
optimum resolution (1600 x 800) for this laptop.
