Right, so having read all your email, there's no reason why we couldn't
just print:

cpu MHz  : 99999999.999

and be done with it.  Sure, it doesn't reflect the reality, but if people
are going to be idiots with it, why not play their game with it to show
how stupid it is.

I don't buy "it's biting us" - I see no evidence of it actually "biting"
anyone.  No one has reported any failures in the last 20 years due to
this missing - and even so as I've already said, it would _not_ be a
regression because that information has never been provided on 32-bit
ARM.

Moreover, I asked what these applications were that are affected by the
lack of us providing this number.  I'm still waiting to hear that, and
I noticed that even you skipped over providing that information which I
asked for, instead giving a hand-wavey answer based on marketing (spit)
people doing stupid things.

Please, try to come up with a _technical_ justification.  I really don't
want to make decisions based on marketing shite which I completely and
utterly despise.
