line in feature_core99_kick_cpu allows the boot process to

MacOS 9.2 booted fine and detected both CPUs.
Compiler gcc 2.96

Kernels compiled with gcc 3.0.2 just crash and go into
open firmware.

Hit http://penguinppc.org/dev/kernel.shtml, and try one of those trees.
There's a few minor differences in the linuxppc_2_4 tree which might fix
this and will be in Linus' tree eventually. And for future reference,
you might have better luck on linuxppc-dev or linuxppc-users

Known gcc 3.0.x/kernel 'feature'.

Which kernel ? Linus 2.4.13 or one of the PPC bk trees ?
I've been using 2.4.13 from bk _devel on a dual G4 for some
time now, it just worked. I'm away from my dev. machines for
a few days, but I'll look into this problem as soon as I'm
back.
gcc 3.0.2 isn't ready for ppc kernel compiles afaik. I'm
personally still using 2.95.4 from debian "sid".
Ben.
