For libata, I think an ATA_FLAG_NO_FUA would be appropriate for situations like this... assume FUA is supported in the controller, and set a flag where it is not. Most chips will support FUA, either by design or by sheer luck. The ones that do not support FUA are the controllers that snoop the ATA command opcode, and internally choose the protocol based on that opcode. For such hardware, unknown opcodes will inevitably cause problems.

This also begs the question... what controller was being used, when the single Maxtor device listed in the blacklist was added? Perhaps it was a problem with the controller, not the device.
