It would save us all a lot of time if you gave an example and worked through the scenario where this is a problem. We already have the choice of having pci_slot built-in, so if there's a bug in that config, we already have the bug. This patch merely removes a config where the bug might be covered up. I don't know why "adding a command line switch" appeals to you as the solution to every problem. As far as I'm concerned that's not a solution to ANY problem. It might be a band-aid to enable users to limp along while we figure out a correct solution, but it's certainly not a resolution.
