I couldn't bring the port back up with any combination of signal/power
cable hotplugging.

Heh.. that rules out drive firmware stuck in wonderland.

Even rmmod sata_promise; modprobe sata_promise failed to bring the
port back up. Hence my suspicion that hardreset is borked or doesn't
kick in.

It looks like the controller requires harder or more proper kick in
the ass to return to sane state.  :-)
