You can find a package containing mmiotraces from the last good and the first
bad kernel revision in the above URL. The traces contain the following marks.

Good:
MARK 11.701343 before begin
MARK 38.640046 nouveau loaded, TV has fbcon
MARK 39.232127 going to start X
MARK 64.224171 X is up, TV has picture
MARK 87.013208 going to change to TV-only
MARK 93.579942 TV is on with full-HD mode
MARK 97.452990 switched to LVDS-only

Bad:
MARK 16.029575 before begin
MARK 46.718026 nouveau loaded, no signal on TV
MARK 47.340368 going to start X
MARK 71.961538 X is up, no signal on TV
MARK 74.445054 going to switch to TV-only full-HD
MARK 84.561667 done, I'm blind
MARK 87.738044 switched to LVDS-only

The command to set the TV-only full-HD mode is:
$ xrandr --output LVDS-1 --off --output HDMI-1 --mode 1920x1080 --set 'scaling
mode' 'None'

The command to set the LVDS-only mode is:
$ xrandr --output LVDS-1 --auto --output HDMI-1 --off

Note that by default Nouveau (fbcon and X) light up both outputs as clones when
it works, just like I've described before.
