Does qtmoko use FSO?  I thought it didn't.  My current (admittedly
pretty weak) guess is that this is an FSO frameworkd bug - in which
case it would have to be different from the QtMoko one.

Also SHR - and I would guess qtmoko - suspends and resumes correctly,
and there is a different open issue about not receiving SMSs after a
suspend.  For that issue, investigation so far indicates something
unexpected about the AT string from the modem, which means that the
root cause of _that_ problem could be the same for FSO and QtMoko.

It is possible that the cause of my problem - missing SMSs _without_
any previous suspend - could be the same, but we don't yet have logs
including the AT traffic that could confirm or deny that.
