I'll be amazed if someone complains. We'll still boot fine on those CPUs without that support code too, we just won't advertise cx8 to userspace, and /proc/cpuinfo won't prettyprint the name. whoopdy-do. Should we actually find someone who a) has one and b) is crazy enough to still run it today, we could always add this stuff back.
