Actually I'm looking forward to the target.

Why use a cross-compiler when you can just use the native one?
I'm not sure I'm going to put the ability to do either in the base
system.

This is true, but I'm not that concerned about the performance hit.

The purpose of the PowerPC effort [at least mine] is not to complete with
Darwin and run on Mac's, but to provide a platform for PowerPC embedded
development. Those that push JKH and others hard for a PowerPC port want
it for use in the embedded market. The G4 would just be the reference
and development box -- but not the main use and target.
I am not sure anyone will take the PowerPC port and polish it for desktop
or server use.
