I'm happy to rip the TAINT parts out. I was just hoping that some tooling might pick up the taint flags today, and this could get picked up without modification of whatever those tools are.
I was _really_ hoping the dmesg from the taint would be ugly and loud enough to be sufficient, but it was relatively terse.

Sounds reasonable to me. As long as we have _something_ that shows up in dmesg, it will help.
