I sent patches to add support ... they were ignored.

Part of the problem is that ATA is heinously broken wrt non-512 byte
sector sizes. You have to know which commands work in multiples of
the block size, and which commands work in multiples of 512-bytes.
There's no easy way to figure it out; you need a table.
