I'm just using the script you provided ... other than that, I don't know what's happening ;-)

Here's what I did, and hopefully you can tell me if I'm misusing it.

1) install hijack over 2.0b11 developer
2) install preinit v3 as per bitt's instructions
3) install empgps and picker in /drive0/bin
4) install your preinit/empgps script in /etc/preinit.d as N30empgps
5) reboot the player.

At this point, I'm presented with the proper picker, I say empgps and I get the gps display. Later I reboot, pick player, and I get no playlists. I also can't get shell access, unending loop in the custom preinit script for empgps.
