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,
