Patch to do that attached.

After setting the master bdaddr on the sixaxis using sixpair, I ran:
dbus-send --system --type=method_call --print-reply --dest="org.bluez" /org/bluez/11043/hci0 org.bluez.Adapter.AddCablePairedDevice string:Foobar string:00:19:C1:61:D6:62 uint32:0x054c uint32:0x0268 string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

Which created the device in bluez. I'd leave it up to sixpair to remove
the device from other adapters, and setting the device as trusted
(though this didn't seem necessary for the pad to work).

Cheers
