That suggests to me that IDE floppy needs to be fixed to open even when no media is present when provided with the O_NONBLOCK flag, which would be consistant with how CDROMs, and everything SCSI works.
As for ide-scsi, I thought that was going to go away?

agreed. But I don't expect to see that showing up soon in 2.4.x, which is what most people (like me) will be using for the next year or two. Sure 2.5.x it might work, but it might eat your disk too. So is groping about in /proc/ide the only way to get reliable ide device detection for 2.4.x, or is there some other way?
