drm messages from 3.2.1

0000:f0:10.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX
5200 Ultra] (rev a1) (prog-if 00 [VGA controller])
        Subsystem: nVidia Corporation Device 0010
        Flags: bus master, 66MHz, medium devsel, latency 16, IRQ 48
        Memory at 91000000 (32-bit, non-prefetchable) [size=16M]
        Memory at 98000000 (32-bit, prefetchable) [size=128M]
        Expansion ROM at 90000000 [disabled] [size=128K]

The monitor is connected to DVI-I-2, but the driver claims output is on
TV-1.

Here's the difference of the kernel output between 3.2.1 and 3.3-rc5:

Reverting commit a0b25635515ef5049f93b032a1e37f18b16e0f6f ("drm/nouveau/gpio:
reimplement as nouveau_gpio.c, fixing a number of issues") (together with
47e5d5cb83d4b41168f4afa1ca32843d4a126cc8,
52c4d767437b40b0cbc02d6a4480abb45ace64bb and
7df898b1a70b13c3a8892625f4ead929d9554293 which depend on it) fixes the issue,
and nouveau.tv_disable=1 is also a workaround.
