Interesting post.

I wouldn't think 3-5 seconds/day would make much of a difference - by the time you hit 'real' amounts of time, your ephemeris would be invalid.

It may be the gpsdriver, but the gpsdriver may just power the device on and off. gpsd is capable of sending NMEA sentences as well, and the maemo 2008 gpsd seems to be a maemo fork (based off an ancient gpsd, from the version number: 1.0-23)

I can't check the link as it now looks like a squatted domain.

as far as time goes, gpsd could reset the time if started with the right flag and ntpdate was configured properly. Otherwise, it is an _internet_ tablet - why not just include ntpdate running under anachron by default?
