looks like a better way to do it, freebsd doesn't matter for us as we
don't have a arm port of that.
I don't know arm much nor can I test so I would need a patch ideally
something that can be upstreamed (so it would need proper guards against
kernels not supporting it)

Though for Debian wouldn't it be enough to change the encoding to what
we are using?
possibly that could be automated by compiling a vand snipped and getting
the code with objdump during configure time.
