Oh, that's probably it.
I got an error from INVARIANTS_SUPPORT (extra 'S') and then failed to 
check in sys/conf/NOTES, did not find it in sys/amd64/conf/NOTES, and 
assumed that the support had been set to "always-enabled" due to some 
vague memory of what hit head.

Thanks for the prompt cluebat.
