Adaptec 1742 is supported, though it took a long enough time to
find its way into CAM. Same for the NCR 810.
For certain applications, also, you _want_ to turn off the automatic
bad sector sparing: it's incompatible with spindle sync, for example,
where you want to spare all drives or none, so that the spindles don't
desyncronize on a sparing hit for one drive, but not another.
