No, you should run the agps-ui before starting the GPS (and close it). If the GPS is running, no assistance data are downloaded.

There are two effects which need to be separated in all this bother about agps and our N810s, one is the crapness of the chipset and the other is possible malfunctions in the agps process.

I fire off Maemo mapper, check satellites in Maemo mapper
6 satellites or 7 sats show up in view.
I go away for 5 to 10 minutes - no satellites in use.
Assuming these were the correct satellites (i.e. it didn't download data for the wrong region, or didn't keep its last set of assistance data), then this indicates that the chipset itself is at fault. The easiest way to check this is to use another decent GPS and check that the satellite numbers initially displayed are the same ones that are locked on to.
