To me both proc and sys work, I'm fine either way.

The issue I had was with the unique silicon ID getting exposed
by default to avoid the Pentium id number situation :)

It's now handled with a Kconfig and cmdline option, basically the
same way as the id on x86. So the issues in the email thread
above are sorted out.
