Out of curiosity, have you tested this with your use case yet? I'm
in a similar boat. Booting 2.6.31 with video=i915:modeset=1 I still
need to stick this in my .xinitrc to get a reasonable resolution:

/usr/bin/xrandr \
--newmode "1280x720" 74.25 1280 1320 1376 1650 720 722 728 750 \
&& /usr/bin/xrandr --addmode HDMI1 1280x720 \
&& /usr/bin/xrandr --output HDMI1 --mode 1280x720

Otherwise the bogus EDID from my old Sony RP's HDMI input results in
a horribly clipped 720x480 with only the center 640 pixel columns
displayed. Would be nice to be able to have the same resolution as
soon as the kernel loads, and on the virtual consoles (without
manually hacking the default VESA resolution timings in the kernel
source)... Reading the commit comments, it's not entirely clear how
you would go about specifying the necessary custom timings (unless
that's explained by the earlier fb patch it mentions?).
