hi I wrote a little webpage[1] with tipps and tricks for using the new debian-installer on powerpc (mostly on newworld macs). If you like to help testing and hacking the new installer have a look at it. The page also contains links to more general d-i informations.
Attention: The installer is not yet stable. You will probably not be able to get a running system without manual intervention. Test and bug reports are appreciated in the BTS and on debain-boot. gaudenz [1] http://www.soziologie.ch/users/steinlin/d-i/
