mark older power managment as deprecated

[Pavel Machek <pavel@ucw.cz>]

Hi!

What about this patch? It marks old power managemnt as obsolete (and
also adds some sparse-style type checking; typedefs were already there
so why not use them?). I think it should go in, so that we can get a
rid of old power managment infrastructure post-2.6.11.
