Two issues that popped up when trying to integrate an AMD machine into

The first is rather straightforward, I think the case was just not
considered during the refactor of the Fixes commit.
The second is part of the resume handling and was introduced when
that restored the register values (DESIRED derived from policy->cur).
My platform seems to handle it well, but it's still strange
behaviour, so why not fix it.
(Also of course the resume value will generally be overwritten and
therefore 'fixed' anyway.)

Thanks for the fixes. I'll pick them up for 7.4-rc2.
