Yes, we /must/ do this checking, if we don't already.

Hell no. If the user asked for mmconfig to be disabled, it needs to be disabled, because it may well be broken and non-working. It's better to not see some capabilities than to lock up the machine.

I think my short response created confusion. I was only saying that we should check for capability overruns, if we don't already[1].

I wasn't saying anything about mmconfig in that sentence, sorry.

Let's pop this sub-thread off the stack, and jump to your "Sounds like a plan?" train of thought.
