Does this mean, it is possible to write a NetBSD driver for a hardware
device without an interrupt (== polled-only)? This sounds very much
like the old harddisk interfaces from way back in 1987, e.g. the OMTI 5520
I had on my A1000. You asked for a certain disk block, did busy-wait
until the status bit indicated the arrival of the disk block and then
had some unrolled loop to read the data from the data register.
