I have a question regarding the flight mode:
if I turn it on (GTA02 qtmoko v47) the icon is shown on the home screen and
calls are not possible anymore, so this is how I expected it to behave, but
the antenna still seems to be on as I see some bars indicating reception
and the power consumption stays the same as without flight mode.
I dont know much about it, but i think flight mode means that you dont transmit
any signal, but you can still receive signal strength.
Modems have AT commands for airplane mode. I tried it on GTA04 (AT_OAIR)
without any effect, maybe i did something wrong...

once was a paper which looked at different parts of power consumption of
the freerunner and if I remember correctly GSM was one of the major
consumers.
You can check yourself - power off the modem and put the phone in suspend and
watch charge_now:

Now if I turn flight mode of the GSM apparently cannot connect to the
station anymore and I have to reboot.
No idea here. I dont use airplanes ;-)

I always meant to hack my install to change it from 'airplane mode' to
'woods mode' because a GSM radio that is out of range of towers devours
the battery. On GTA02, power consumption drops a lot in this mode.
On my most recent trip I powered my GTA04 off completely unless I needed
to check the GPS.
On a trip this winter a friend with a certain apple product was amazed
at the battery life they got in airplane mode. 3 days of photo-viewing
and listening to mp3s and it still had extra battery.
