Not as far as I can tell. In principle these should be supported
by gem(4). What needs to be done to make them actually work is:
- figure out the register layout (apparently it differs somewhat
  from the PCI variants) and add an SBus front-end,
- add support for the SERDES,
- make some performance improvements like adding support for
  checksum offloading and converting the TX side to use
  bus_dmamap_load_mbuf_sg(9).
