1043:814e is also P5GD1.
It was changed to ALC880_ASUS based on the report in the above.

I believe it's fine to change to 6stack model if the tester's board is
also P5GD1 indeed. Of course, it's possible that ASUS may change the
hardware design completely for the same model number with PCI SSID,
but I hope they aren't so crazy :)
