Maybe we should set a taint bit or give some other indication that we're using a flag to work around breakage. There's a big difference between parameters like "root=", "console=", "quiet", etc., and the ones like "pci=nocrs", "pci=realloc", "acpi=off". The latter are basically workarounds for deficiencies in Linux or the platform, and we should try really hard to minimize their use. We might need some of them as interim workarounds, but I don't think we should regard their use as acceptable standard practice for end users.
