This lets you force the setting for various gconf controlled applications.
Works great to force users to lock their screens as well. :)

However, it appears that (from my quick test of unplug/replugging a USB
card reader) are actually messages sent via dbus on the system bus from
HAL, so the correct implementation would be to disable broadcasting
those messages in the first place. Given that some things like avahi are
system messages that are useful, I'd suggest looking at the hal config
first.

I don't know enough about the system to make changes, but suggest taking
a look at the following files:

/etc/dbus-1/system.d/hal.conf
/etc/dbus-1/system.conf

Hope this helps.
