I'm using nfsroot (no modules), .config is attached. Debian v7.7,
ofono installed.

To launch ofono, I'm using:

rmdir /dev/cmt
ln -s /sys/bus/hsi/devices/n900-modem/ /dev/cmt
killall  ofonod
sleep .1
ofonod --nodetach --debug &

# enable the modem
mdbus2 -s org.ofono /n900_0 org.ofono.Modem.SetProperty Powered true
# enable modem's RF parts
mdbus2 -s org.ofono /n900_0 org.ofono.Modem.SetProperty Online true
# scan for available networks (takes some time)
mdbus2 -s org.ofono /n900_0 org.ofono.NetworkRegistration.Scan

I do have working SIM card in it. (Alternatively, ofone button
"online" can be used).

Good luck,
								Pavel
