Hey thanks. This is totally something I hoped would eventually go upstream,
but I never got around to cleaning it up enough for mass consumption beyond
the use case we had in mind (beating certain folks over the head when they
have "value add" in BIOS code that causes huge SMIs, and the like, for RT).

Did anyone ever get back to you on this one? I never saw any followup. I
will be happy to do some testing and help you get this mainlined.

Jon.
