I dunno, we also saw the case where a bunch of people found KMS caused
freezes, so we turned it off by default on those chips, and subsequently
a different bunch of people with the same hardware turned up to say
turning it off caused freezes for them.

Who knows what other problems could exist in the non-KMS case; we've
been running with KMS enabled by default for most of the release, so
blindly switching it off at this point seems like playing Russian
Roulette.

I think the better approach is to understand exactly why the freeze
happens and fix it. After all, at some point there won't be an option
other than KMS so this bug really does have to be fixed.
