Because 'gpsdriver' seems to be some kind of middleware between userspace
applications and kernel driver. It powers On/Off the GPS, uploads also
something like GPS Almanac data from /var/lib/gps/nvd_data to GPS driver and
it seems, that it also writes back this blob when the GPS is about to shutdown.

No, but there's battery applet which needs to read that info from somewhere...
