That's definitely wrong. pppd doesn't have to wake up for each packet
sent, unless you have very strange options set. Not having 'asyncmap
0' might be a cause. What's in your /etc/ppp/options ?

femto[~]$ fuser -v /dev/modem
femto[~]$ fuser -v /var/log/*.log
femto[~]$ su -
Password:
RoOt@femto[~]$ fuser -v /dev/modem
USER PID ACCESS COMMAND
/dev/modem root 11256 f.... pppd
RoOt@femto[~]$ fuser -v /var/log/*.log
USER PID ACCESS COMMAND
/var/log/auth.log root 77 f.... syslogd
/var/log/daemon.log root 77 f.... syslogd
Perhaps that was your mistake? From the fuser man page:
fuser may only be able to gather partial information
unless run with privileges. As a consequence, files opened
by processes belonging to other users may not be listed
and executables may be classified as mapped only.
