I remember reading at > least one post to lkml from a company who is using the Taskfile ioctls and I know several people using them, and for some ioctl operations they are required. In fact without taskfile ioctl stuff I can't make my laptop resume correctly for example. (it needs proper drive please wake up sequences to go the ibm microdrive) At this point I think you've overstepped the mark. The taskfile stuff is rather important. If you don't understand why please read the ATA6 standard and look at the sequence of phases. Think of it as a scsi sequencer in kernel space because the hardware isnt bright enough to do it.
