ev56 will break compatibility with many supported older machines.
What happens with releases and packages?
This situation is a bit different than loosing 80386 support in
the binaries where we can expect owners to have acces to at least a
pentium to build the binaries their self.
Please add at least a note in UPDATING so non BWX owners don't
forget to update their /etc/make.conf.
EV6 would be a bad default as it includes Multimedia extensions which
are not available on ev56 machines and exclude much more machines
without such a big performance win.
Also it would break kernel builds as we explicitly tell the assembler
to understand ev56 assembly - maybe it's a good idea to just raise that.
