autoloading sg driver during boot

[Aleksandar Milivojevic <amilivojevic pbl ca>]

Probably something trivial, but can't seem to find solution (other than 
placing "modprobe sg" in /etc/rc.local).

I attempted something like this in modprobe.conf:

alias char-major-21 sg

(and also char-major-21-* variant)

The problem is, there are no /dev/sg* entries in /dev when machine 
boots.  They are created by udev when "sg" driver loads.  Chicken and 
egg problem.  Kind of.  So the above lien in modprobe.conf does not 
really work.

So....  the question is, is there any way to instruct udev to create 
/dev/sg* nodes (so that applications can access it and trigger auto 
loading of sg driver)?  Or instruct system to autoload sg module during 
boot if there are any SCSI devices, which would trigger udev to create 
/dev/sg* nodes?  Other than placing "modprobe sg" in /etc/rc.local.
