In the kernel for PPC, a lot a code is here just to do what doing RTAS :
pci config,
via (CUDA and PMU) (no need if no ADB keyboard), ...
When doing embedded systems, this drivers is very big and can be saving by
using
RTAS which i think is a very good thing in  CHRP specification. It's
strange that
apple do not provide it fully.

Well, they didn't care about it. Note that Macs are far from beeing
embedded boxes ;)

Yes, but i'm using embedded term for small system that doing dedicate task
and only one (for example firewall, gateway, ... in only 50-100k kernel size).

I'm actually experienced that with G4 with 4 network card.

And what's the smallest amount of memory you can put in a G4? I guess it's an
order of magnitude larger than a kernel containing all possible drivers :-)
