And a working 686 distribution is a great deal more useful to end users, who outnumber you by a few million to one. It's a very sensible patch, or perhaps you'd prefer we didn't say. And you forget the user "debug" for a Geode + i686 without this will be "it hangs when I try and boot the install CD" It would probably also be worth having cmov fixups for the VIA C3 as well.
