Yes, from my original post, I'm running debian;
# cat /proc/version
Linux version 2.6.29-20100313.git973a41fc (root at neo) (gcc version 4.4.5
20100728 (prerelease) (Debian 4.4.4-8) ) 1 Sat Aug 7 17:45:57 GMT-3 2010

with frameworkd running ogpsd.  The frameworkd log shows a position (which
I've obscurred):

2010.10.01 01:39:08.43 ogpsd                DEBUG    Got UBX packet of type
NAV-POSLLH: [{'LON': -123xxxxxxx, 'HMSL': 28843, 'HEIGHT': 11546, 'ITOW':
463141000, 'LAT': 48xxxxxxx, 'Vacc': 999998976, 'Hacc': 999998976}]

Is this position just the persistent data, or is ogpsd actually getting this
from the gps chip?

I find it odd, that the frameworkd/ogpds logs show a position, but if I
query the position from the dbus interface, I get nothing.  For example:

# mdbus -s org.freedesktop.Gypsy /org/freedesktop/Gypsy org.freedesktop.Gypsy.Position.GetPosition
(0, 0, 0.0, 0.0, 0.0)

Last time I did a pacakge update (Friday), debian _removed_ fso-gpsd.  Does
anyone know why?  It seems to be mutually exclusive with tangogps/foxtrotgps
in the package dependencies, which I don't understand, because as far as I
know they rely on fso-gpsd (i.e.  they aren't written for the dbus interface
