Unless you think that it will be helpful to test with the workaround, I would prefer to test patches from llvm (it takes days to build FreeBSD on a net5501...). This proves it is useful to test with uncommon hardware, and I would like to check the crypto engine, hifn(4) and glxsb(4) built with llvm (that worked fine around january). Thanks a lot, regards.
