Andreas -- I just recieved the following from a PPC engineer at IBM:

"I don't think it is possible to build a ppc kernel with just
CONFIG_PPC_MULTIPLATFORM set. You'll need to "choose" another compile
option such as "cell" or "iseries" or "pseries" or somesuch (from
arch/powerpc/platforms/). Check arch/powerpc/configs for the relevant
defconfigs."

... so it looks like this is currently limited to ia64 ...
