I think 2.2.10 from vger will now, and paul m put up his 2.2.10 tarball
which works as well.  Keep in mind there is some "wacky" problem with the
new B&Ws.

The patches (which have been fixed up and included in vger now) which YDL
made are on their site, along w/ the dot.config.

Hmm.  That is very odd.  The Blue&White kernel supplied w/ R5 works on
mine, as does the 2.2.10 Paul put up.  Give Pauls a shot..

USB in vger won't work.  Paul's endian fixes aren't in yet (2.3.x or
2.2.x), so use his tarball.

B&W's need CMD646 and Pmac-ide suppoprt right now.

The 2.2.6 sources use Inkay's uusbd, which is now defunct.

I can't think of anything I forgot above.. :)
