I think 601 support itself is done.

The real problem with supporting older machines is different. It is that=20
they don't have OF, and macppc currently assumes we have a working OF=20
around. Thus our current code base will never work.

We could, however, go to an approach where we keep an internal OF tree and=
=20
read properties out of it. Then all we need is for the booter to pass us=20
such a beast, and we're set. This behavior is what MkLinux does as I=20
recall.

RTK makes (or made) devices which had issues that rendered them=20
exceptionally low-performance. To the extent that if you have one of these=
=20
cards, you really should just buy something else. I think the newer cards=
=20
aren't as bad, but they still cut corners and it shows.

Take care,
