Is there board specific code to go along with this?

Nope.

When I enable I get:

arch/powerpc/kernel/built-in.o: In function `cpu_idle':
/home/galak/git/master/powerpc/arch/powerpc/kernel/idle.c:98: undefined reference to `cpu_die'
make: *** [.tmp_vmlinux1] Error 1

This isn't caused by hibernation or my patch specifically.
Instead, it's a long standing issue, enabling CONFIG_SMP and
CONFIG_SUSPEND is enough to trigger this. Patch exists:

No idea why it didn't make Linus' tree.
