Hello,

Some weeks ago I acquired a second GTA02 and installed SHR into it; they
both behave different in some hardware related aspects:

1:
The older one (running Om2008.9) needs a press of ~8 secs to boot, the
newer one (with SHR) on a short press of the power button makes a
short sound, then a short vibration and boots up;

2:
The older on GPS needs 1-3 minutes to get a 3D Fix, the newer a few
seconds, sometimes less than 10 secs;

the cpuinfo details are below; Where does this come from? Thanks
