I have to say, that with my main goal for 2.6.20 being a stability release, and the APIC setup scaring me too, I'm starting to strongly lean towards just reverting the thing, and then having this whole thing re-introduced early during the 2.6.21 cycle with the new information we have (ie the clues about exactly why the dang thing broke in the first place). After all, the only reason I didn't want to revert the commit initially was that it did clean things up, and I wanted to understand why it didn't work. I think we understand why it caused problems, and I think we can fix them, but on the other hand, we're already deep into -rc4 with this, so let's just revert for now and then clean it up correctly after the 2.6.20 release.
