Oh, then I missunderstood you. I thought that the kernel is built
seperatly for every subarch.

I would propose to modularize as much as possible. But as I never built
a fully modularized kernel I don't know if there are any drawbacks. 
Probably we should discuss this on debian-powerpc.

No, we need udebs for every module that has to go into the installer
For arches which need the initrd built into the kernel it works the
other way around. First you build the initrd and the you compile the
kernel with this initrd embedded.
