	The simplier method to get an interrupt from the tape controller
	is to load tape, move in forward for some seconds, press REWIND
	and quickly switch drive ON-LINE. When it'd reach the physical
	marker it'll generate interrupt. This trick works as a rule.
	(Anyway the better solution is to hack up driver to make it
	to do timeout-s on operations ;-).
