On my x220, I would agree that Timo's kernel is at least as good as any of the others I've tried (Martin's, 3.0.1.2 from oneiric). Suspend and resume works. Trying to enable both monitors leaves large black areas that are not drawn into, but I think that might be a unity problem.
The summary of this bug seems to no longer reflect what is being discussed (arrandale vs sandy bridge, desktop vs external) -- is it really the same problem?
