So far the check_feature() function compares the subfield of a CPU ID register against 0, to learn if a feature is enabled or not. This is problematic for checks that require a certain revision of a feature, so we should check against a minimum version number instead. On top of that we might need to add code to support newer versions of a feature, so we should be alerted if new hardware introduces a higher number. Extend the check_feature() function to take two extra arguments: the minimum version, and the greatest currently known number. Then make sure that the CPU ID field is in this range.
