to force 4KB sectors?
No need to implement that, it is in -CURRENT (did not check -STABLE).
But there is no quirk, that disables NCQ, currently, although it is
easy to implement. See the places where "ADA_FLAG_CAN_NCQ" is set and
make that value depend on a new quirk flag being unset ...
But instead of setting that flag in the loader, it would be good to
collect drive signatures that need it and to add quirk entries for
them in ata_da.c ...
