oFono has so far only released version 0.50 upstream, so I'm not sure
how Meego is making 0.58 ;)  Try putting plugins/ofono.rules from
ofono.git into /etc/udev/rules.d, re-plugging your dongle and starting
oFono with -n -d 'udev*'

Nope, sounds like the rules are not installed or the card is not
inserted (but I assume it is built-in, so the latter is probably not it)
