There seems to be a lot of code in the IDE subsystem relating to
interrupts. Is there a way to set a device in polled (i.e.
non-interrupt) mode? Maybe some way to run the tasklet/bh
periodically?

Does the IDE system want to monitor my ATA device's Ready_NotBusy
interrupt?

No, linux IDE layer can't do that in a sane way, you are asking for
a _lot_ of trouble... (especially if doing DMA)

"No" there isn't a way to set the device into polled mode, or "No" it
doesn't monitor the Ready_NotBusy interrupt?

Can't you use the Ready_NotBusy interrupt as IDE interrupt?
