Yup. There was (what I thought was) a bug in the existing logic (an
explicit match on "ndiswrapper", and a setting of the global kernel
taint flags) and I corrected it to do what I thought it was actually
intending to do, but hadn't been. Was I mistaken? What's the point of
setting the global taint if we don't know why we set that?

Yes it is. But I thought the existing code was intending to taint the
kernel (that's what it does), so it would really help to identify why it
tainted the kernel, by calling add_taint_module instead of add_taint. I
didn't put the existing match in there...don't shoot the messenger :)

Another fix would be for ndiswrapper to explicitly set the taint when it
loads a tainted driver? Or do we just want to go back to globally
"tainting" the kernel without assigning the blame to any module?
