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.
