BTW... The basic trajectory these days is not to be so careful with
32-bit-only gunk. If it's causing us any headache -- even a few lines of
code -- it better be unambiguously crucial to functionality to stick around.

In this case, the guy still running a Pentium classic is highly unlikely
to be concerned about the kernel forgetting to add an F0 0F workaround.
There are also unlikely to be Pentiums sitting in data centers with log
monitoring tools that are desperately looking for that F0 0F hunk in dmesg.

The most likely thing is: there are a few dozen Pentiums (if that) out
there running mainline kernels. I'm not sure they even have more than a
couple of distros they can run. Nobody is going to notice this message
going away.
