Looking at the important piece:

-----
it seems to me that using 4 for t.setup also should be done unless _all_ devices
on that cable are ide_disk. In particular, if one device is ide_disk but the
other is not, then "t.setup = 4;" should be used even when talking to the ide_disk.
Otherwise the non-ide_disk device might get confused, respond when it should not,
and garble the transaction. Or, is such a bad thing prevented in some other way?
