Hi Dennis,

thanks for your hints.
I found out, that is mainly fbdev which costs the high CPU load.
with x11 and no rotation I get 60% CPU at 10fps and a fluent movie.
x11 and rotation is about 80%CPU.
fbdev is at 80-90%CPU with or without rotation and a not so smooth video 
any more. 
xrandr -o 2 seems not to work.

So I can live with that - after all it's actually only a 'proof of 
concept' without any relevant importance ;)

I also updated to a new image (last one was more than 1 month ago) and I 
was surprised about the speed improvement - launching applications and the 
reaction time of certain controls (especially disabling dimming and 
suspend) are really impressive now! However did this - thanks a lot, I now 
hate my freerunner less than before ;)

Just one strange thind to mention: opkg update/upgrade from my prior 
version crashed my phone and the power button started to shine in magenta! 
Never seen this before, but it was really nice.
(We could use this if the SIM card was detected as TCom provider...)

Alex.
