QtMoko is Debian based, isn't it? The "correct way" of dealing with
"do something at shutdown" problem would be to write an init script,
put it in /etc/init.d/ and symlink to appropiate runlevels
(/etc/rc0.d/ for shutdown and /etc/rc6.d/ for reboot). This is the
standard way to stop services during shutdown and stopping modem IMO
fits pretty well into that process - and it doesn't feel like a hack
like previous propositions here.
