What's in a name?  GCC can define it as march=hamburger but that doesn't
make it so, it's just a name of convenience/convention.  I assume
Intel's specs/contracts define what is/can be called an i686, so if they
say it's optional then the C3 is still a legit i686 even if CMOV support
is more common.

Well, if ya wanna make a fanless i686 (ish) CPU that runs on five (5)
watts or less, you gotta leave a few things out.

This just means my legacy app is stuck on a 60watt beigebox instead
(since VirtualBox's serial port support is broken).

Thanks anyway.
