If this is a bug in NetBSD, it's also a bug on this Linux:
Linux eternium 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u4 (2015-09-19) x86_64 GNU/Linux
model name : Intel(R) Core(TM)2 Duo CPU E8600 @ 3.33GHz

implemented and working. According to:
the AVX flag (bit 28) also needs to be asserted.
