The most serious ones were for were for ATAPI slaves.

Apparently, whether the slave registers are visible when the master is selected depends on the jumper. I forget what the ATA standard specifies. Anyway, the problem was "fixed" in -current by making the code controlled by the ATAPI option non-optional.
