Thanks for the info.

OK - as a test I'm going a very different direction. As there is a
prebuilt Ubuntu PowerPC version I've just written a CD and it boots
fine. I'm right now in the process of letting it blow away my
non-functional Gentoo install and install Ubuntu. If that boots then I
can see what they did and redo Gentoo later with that knowledge.

As for using Gentoo on this box I'm not sure it's really worth it any
more. My main machines now are all x86_64 - as is probably true for
most people - but fast ones - an i5-661, i7-920 and an i7-980x where I
run 5 copies of Windows 7 at the same time in different VMWare jails.
I found I wasn't updating this old Mac Mini because it was too slow
and took too much of what I call 'Gentoo effort'. If I can find a
prepackaged version of MythTV for this machine then likely I'd be
better off just to run Ubuntu. I don't really need performance for a
MythTV backend server.

Anyway, I'll report back more when I know more.

Thanks!

Cheers,
Mark
