This seems like a risky assumption...
Its wrong on various counts
- ata_id_major_version can't tell early ATA versions apart
- on anything later than the early ISA IDE paddles (the ones that
basically were just bus decoders) its invisible to the drive
Except for legacy ISA bus controllers (and even there it is questionable)
I would favour simply ignoring it.
32-bit IO wouldn't work on any ISA controller, would it? What happens if
you do 32-bit IO port access on something on the ISA bus?
