As much as I appreciate the idea of splitting the patches and
getting something in sooner rather than later, I'm concerned
because without quirk handling, this code is effectively useless
on 60% or more of available server hardware platforms.

If we're going to split the review into two threads, it can't be
an excuse to drag out the quirk handling for months.
