This did it.

Reverting that commit (or booting with sata_nv.adma=0) fixes HPA for me here... Robert, is reverting that commit going to crush my little world, or is it a safe course of action? I'd rather not disable ADMA (which turns off NCQ, right?) wholesale, as the whizbang-gentoo crowd will hang me.
