Tells devfs to load the 'sg' module if /dev/sg* is accessed

Basically just set the permissions to 0660, and ownership to root.disk
when /dev/sg* is registered (the generic scsi module loaded ..)

We have the PERMISSIONS entry in our /etc/devfsd.conf:

-----------------------cut-------------------------------------
# Give the cdrw group write permissions to /dev/sg0
# This is done to have non root user use the burner (scan the scsi bus)
#REGISTER        ^sg0$       PERMISSIONS root.cdrw 660
---------------------------------------------------------------

Just commented by default.  As I always have my generic scsi into
kernel, I am not sure that first line is really needed, as there is an
alias in /etc/modules.devfs.  Will try to find the time though to
verify it.
