I haven't collected any known reports yet. That happens later, I
thought, nearer to RC1.

Yes, but to throw an error if spinlocks aren't found, we need this
patch. We would have to test for Opteron in all the platforms that test
for specific CPU's but don't test for opteron, and might support
opterion/itanium, but even then, we don't have any way of getting a
report of a failure.
Yea, I should have thought of this before beta1, but now that I see the
bug reports, seems we have to go this way.
