Hi,

git://gitorious.org/gnutoo-s-programs-for-shr/xf86-video-omapfb.git
contains code for making rotation work under devices with omapfb.

Requirements:
 * "omapfb.vrfb=y" in the kernel arguments.
 * A GTA04 (tested only on GTA04 for now)

Issues:
 * break XV
 * Input does not rotate(you need to do it manually)
 * Rotation can take a long time.
 * Fullscreen games are problematic in rotated mode: they don't occupy
   all the screen. I'm working on it right now.

I use 2 scripts for rotation:
root at om-gta04:~# cat rotate_o_1.sh 
export DISPLAY=:0
xrandr -o 1
xinput set-int-prop "Touchscreen" "Evdev Axes Swap" 8 1;
xinput set-int-prop "Touchscreen" "Evdev Axis Inversion" 8 1 1;
xrandr -q

root at om-gta04:~# cat rotate_o_0.sh 
export DISPLAY=:0
xrandr -o 0
xinput set-int-prop "Touchscreen" "Evdev Axes Swap" 8 0;
xinput set-int-prop "Touchscreen" "Evdev Axis Inversion" 8 0 1;
xrandr --dpi 280

1) run the script
2) wait a bit
3) touch the screen to make the image appear.
