True.

There are plans to get Debian on ColdFire with MMU.

I can easily boot ARAnyM on my laptop at home. I guess I’d get
about 20 emulated MHz.

As Geert said, the clock rate is guessed from the BogoMIPS
value, which by the way is only calculated at startup and
in a VERY short time, so is wildly inaccurate. Virtualisation
hosts with varying load will have unusable values there; I’ve
started to use python’s built-in benchmark to check which VM
to use before building gcc or linux now…
So far, the only good idea was to check for existence (and
possibly usability) of the natfeat instruction, I think.
The goal is to be able to check for emulation/virtualisation
WITHOUT any special setup.
