I'm embarassed to say, though not too proud to admit, that the power cables weren't properly seated. It's working just fine. I have another question, though. I've patched the ide driver to permit an IDE interface to operate without an IRQ. It needs a little bit of tweaking before it will be accepted by that IDE maintainer. Are you planning to subsume all of the IDE functionality into libata that is handled by the other IDE driver? If so, have you considered adding polling mode? Cheers.
