Is this with a Freerunner?  Do other Freerunner users have GPRS working?
If so I'd suggest logging and comparing your log with theirs.

Are openbmap and cellhunter implemented yet for QtMoko?  I thought they
were implemented for FSO-based distributions only - i.e. SHR and
FSO-based Debian - and in that case the access to the modem is managed
by FSO.

Yes, that would be a useful feature.

I think there are pieces of QtMoko that do that scanning, so the
question would be how to connect those with your work.  I'll try to look
into that a bit more.
