ok, but wouldn't it make sense to still have these both gpios at least as
By the way: I updated to QtMoko v53 in order to make the tests with GPS.
First thing I had to find out after update is that Terminal console does
not work any more on QtMoko v53. Trying to call it does only result in an
restart of QtMoko v53. ssh-console still works.

They're gone since 3.5, as Neil Brown's GPS driver handles power-on/off
and antenna switches automatically. Please refer to  for further
Just open /dev/ttyO1 and GPS is powered on. Once no process has
/dev/ttyO1 opened anymore GPS is powered off.
You can find some info about the antenna in /sys (I don't remember the
exact path though, just grep for "gps").
