Sure, they could be nice enough to have a flag to disable the check for
non-intel cpus. That way intel could avoid the cost of testing/certification
of AMD cpus and folks that want to take the risk could. There is a binary
floating around that patches binaries to avoid the check. Improvements were
on the order of 0-15% I believe, nobody reported wrong answers as a result.

Well the issue wasn't intel not doing AMD specific optimizations, it was intel
enabling optimizations that would benefit both CPUs, only when running on intel.
