Nice,
Some comments:
Instead of requiring modification to /etc/devd.conf why not just put a
"plugin" conf-file in /etc/devd/ - well even better put in
/usr/local/etc/devd/ - that way your devd.conf modifications are not
lost upon patching/updating base os.
There is an existing port called "automounter" by Dominic Fandrey which
is much similar to your work.
You can get inspired of how he places his devd.conf in /usr/local/etc/devd/
His "automounter" also works with disk labels (as found in /dev/ufs/ and
/dev/msdosfs/ etc)
You should consider make a port out of your work.
