After a little more digging, I came across the original reporter's correspondence on the linux-ide mailing list which determined because the adapter appears as a generic JMicron PCIe to PATA controller, it couldn't be reliably whitelisted without affecting other devices with the same controller. For reference, the workaround is to use module parameter libata.force=80c.
