Yes, it does, AFAICS.  It didn't change the bits that weren't directly
related to suspend/resume (at least that wasn't the intention).

That said, using sysdevs for the initialization of things the way you describe
will have to change anyway, because sysdevs are going to be removed entirely
from the kernel at one point.
