I haven't got enough time today to translate every of his posts but I'll 
do it for the last one ;) Sorry for my quite "rusty" english, has 
already been some time that I've translated something ;)

Hello alltogether,
yesterday at night I flashed a new kernel image to the Freerunner, which 
should support some kind of suspend mode. Unfortunately it doesn't work 
with the ASU Image, so I had to put back the Openmoko Image I had 
before. It's looking good by now. Now 6,5 hours passed and the battery 
is showing halftime! I'm anxious to how long it will last in the end! 
Concerning the suspend mode, I'm not sure if the Freerunner will go into 
this mode, but the display is totally shut off. Before it has only been 
very dimmed, but at night you could see that it has been on.
Also positive is, that at an incoming call the display lightens up and 
shows the dialer, so you won't miss the right button :)

Okay, I've returned tonight 12 hours later and the Freerunner's battery 
wasn't fully drained yet. The battery indicator was very low but it was 
running. This gives more than 12 hours of lifetime. All this has been 
possible thanks to the kernel images from here:
Though I think, that the CPU has not been clocked down and so on.. I'll 
try out another more detailed lifetime-test - something like constant 
telephony up the bitter end ;)
