Admittedly, my commit message re: it already being in GENERIC was wrong. It being in x86/NOTES is what mattered.

Apple sold very few i386-based Intel chips before they transitioned to amd64-only ones (it was only a matter of 8-9 months IIRC) and asmc(4) doesn’t support any of the 32-bit chips (I checked).
