>Description:

	repeated use of kldunload and kldload with most
	of the syscons screen savers causes panics.

>How-To-Repeat:
	assuming you have the daemon saver installed already ...
	this triggers it for me, same for fire saver but not
	for the green saver, not tested many others as this
	is the only machine I've got and don't fancy the bad
	luck of file system damages.

	for i in /
	do
		vidcontrol -t 1
		sleep 4
		kldunload -i `kldstat | grep daemon | awk '{print $1}'`
		kldload /modules/daemon_saver.ko
		kldstat
	done
