Hi all,

I've attached a patch for the macppc port's hardware notes
(/src/distrib/notes/macppc/hardware) to try to bring it up to date for
the 4.0 release.

A summary of my changes:

- Updated the supported hardware list to include newer Powerbook G4
models, the Mac Mini, and various G5 models.  (Basically synced it with
the separate web page that provides this information, though there are
probably still differences.)
- Added a caveat about the fact some of the newest G4 models do not
necessarily run at their full CPU speed.  (This is also consistent with
the note on the model support web page.)  I assume that this is still
relevant for 4.0, the last email I could find on the subject is here:
- Added a caveat that G5 models are only supported in 32-bit bridge
- Revised unsupported model list to reflect changes above.
- Fixed three references to ethernet devices so their "proper" names are
- Added note that wscons capabilities are now available.
- Also supplied caveat that wscons does not support VT switching while
X is running, reference:
- Added the snapper driver to the list of supported devices.
- Slightly revised the comment about awacs being an experimental driver.
- Fixed a nroff glitch under serial ports that was causing two words to
be rendered without a space between them in the HTML output.
- Updated list of unsupported devices, removing some, and adding a note
that the SATA controller on G5s is not supported, reference:

This is based on what I know from reading the port-macppc mailing list,
and so may not be wholly complete or accurate, but I thought I'd take a
stab at it.

A few things I didn't change but have questions about, as they may be

- Does the awacs instability caveat really still apply for releases
>=4.0?  (I don't have a machine with awacs, so I can't test.)
- Under unsupported devices, should advanced power management be
qualified or updated?  I infer there has been some progress here.  Or
am I confusing power monitoring and power management?  I use the
former but not the latter on my iBook right now.
