mrg 2aba26f773 - auxio cleanup and sbus support.
- make GENERIC64 include GENERIC and set the 3 optoins it needs.  suggested
  by hubert feyrer.
- add a comment that we maybe should use the `bpp' driver, not the lpt, on
  the ebus because the `bpp' driver does DMA already.
- ebus_attach_args got a member renamed
