PATCH 1/1 CONFIG_PM for ppc64, to allow sysrq o

For some weird reason, sysrq o is hidden behind CONFIG_PM. Why? One can power off just fine without that. Can pm_sysrq_init be moved to a better place? I think it used to be in sysrq.c in 2.4.

Too bad, with this patch radeonfb fails to compile.

After disabling radeon and this additional change, sysrq o powers off. Just dont type too fast over hvc (ctrl o o) ;)

Hehe :)

ppc64 isn't yet ready for CONFIG_PM, though I have some hacks-in-progress ...
