More in the hardware: it does not have (IIRC) an interrupt status register
that could indicate "yes, I requested an interrupt".

The lpt driver will not claim an interrupt if the hardware does not indicate
the printer being ready or having an error condition. This could be considered
bogus - maybe we should just declare "lpt can not share interrupts" and have
the driver always return 1 from the interrupt handler.
