It is still the case, for the most part. -rt works fine on both ppc and
mips, just not in qemu.

The first port of any new kernel, I carry support over exactly as it is.
Only changing the kernel + headers, stabilize the existing support and
then look at adding new functionality and boards. That's the only way to
reasonably control the changes.

Cheers,
