The DTC-3181E/NCR53C400A support in g_NCR5380 sucks, since it locks
the machine (X mouse stops, no keyboard input possible) after e. g. a

	mtst -f /dev/tape rewoffl 

until after the tape has been rewound and thrown out. Note: using
DTC-3181E without interrupt since I haven't yet figured out how to
enably IRQs on that Relisys 16D3 (3181P) thing. Seems to work fine
however. 

Something like that IDE unmaskirq feature would be great, but I don't
know how to do it.
