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]
Memory at d0000000 (64-bit, prefetchable) [size=256M]

[virtual] Expansion ROM at c0000000 [disabled] [size=128K]
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.</pre>
