BTW - for everyone's edification, here is a report on fedoraforum.org
that looks suspiciously like the same problem we're dealing with:

http://forums.fedoraforum.org/showthread.php?t=255025

The mobo worked with F13, broke with F14, nothing he did seemed to
bring the keyboard back, ended up fixing it by getting another
brand of motherboard.  I'm going to see if I can find a copy of
that motherboard for testing...

No, the original mobo worked on F13; new mobo broken on f13 & f14.
It sounds like an intr-rewiring problem; note, that he got it booted once,
(in the thread) and it took 30mins to do so.

Hmmm... would it be better to do this as a quirk or as a boot

Hearsay?  if you have definite cases, then please share them,
so folks know when to flip the boot parameter on.  note: it would
have to be
an early boot param as well.

It'd definitely be good to know all the specific cases.

But merely sharing them so folks will know when to use the parameter
is a broken model.  We should make it work automatically, either with
some sort of machine-dependent quirk, or (preferably) with a change
to
the generic algorithm so it can handle these "broken" topologies
along
with all the correct ones.
