Ah, yes, I should have been more clear. I want to get this patch upstream so we can get it into stable, so that we can get it into Ubuntu 10.04. Certainly what I'm proposing is suitable for stable: it's minimal, specific to a few machines, etc. For the long term, I support the patch that Matthew sent out yesterday, and we can perhaps think about removing the quirks entirely. Thanks, /ac
