we can do a seperate idle driver; it'll still be x86 specific (since idle really is arch specific)...
and then the umwait parts of this will be Intel specific.. as well any future idle methods ..
and I'm not sure the AMD folks would even want it used .... at which point it ends up Intel
specific fully and we now have 2 Intel idle drivers.
I don't see how that makes sense.
