My understanding is that, by default (GENERIC), sg device is not
compiled into the kernel, so, in order to use it, you may have to
compile your own kernel and add:

	device sg

In the configuration.  The device would appear as "/dev/sg0", etc.;
Linux style "/dev/sga /dev/sgb" would appear as symlinks.
