Dual-Head is not working on my NV50.

If hot-plugging the second display and xrandr-enabling it, both screens do not
get any signal. switching (or trying to switch) to another vt does not work
(still does not display anything). Keyboard LEDS still work, but no keystroke
does anything. XRandR shows correct information for both displays though.

If cold-plugging, there it does not display anything either (in plymouth,
then).

In either case the System is still responding to ssh and can be shutdown
gracefully. There is no error in dmesg and Xorg.0.log.

I might test this with an uptodate nouveau-drm and x11-drv-nouveau next week,
but I cannot promise I will have the time.

Some details:
. both displays connected with DVI-I (e.g. DVI-I-0 and DVI-I-1)
. using Fedora 11, uptodate on 9th september 09, with packages
xorg-x11-drv-nouveau-0.0.12-40.20090528git0c17b87.fc11.x86_64
xorg-x11-server-Xorg-1.6.1.901-1.fc11.x86_64
kernel-2.6.30.5-43.fc11.x86_64
