[Gta04-owner] Small update to Debian/LXDE/2.6.32 image: made Tangogps work

[Dr. H. Nikolaus Schaller]

There is a fix for the /root/gps-demo script so that it now

* correctly initializes the VSIM regulator to power up the internal/external antenna
* resets the GPS chip through a GPIO if it is not sending NMEA records
* initialize gpsd on /dev/ttyO1
* launch TangoGPS (FoxtrotGPS)

Here is the script for those who are looking for sample code:

http://git.goldelico.com/?p=gta04-rootfs.git;a=blob;f=debian/config/root/gps-demo;h=4be4e694adb40324755427bbe41f6d566ab3b9de;hb=HEAD

It should also be available through apt-get update/upgrade (if the goldelico server is still included in /etc/apt/sources.list).

PS: this most likely does not work with the 3.x kernels since they handle GPS and GPIOs differently
