SVN rev 199273 on 2009-11-14 16:20:07Z by mav
Previous solution appeared to be unsufficient. After additional testing
I have found that it is not only desktop CPUs problem. but mobile also.
Probably AP on laptops just started initially at lower frequency, hiding
the problem.
Disable frequency validation by default, for systems with more then one CPU,
until we can implement it properly. It looks like making more harm now then
benefits. Add 'hw.est.strict' loader tunable to control it.
Now my iXsystems Invincibook is able to run at 800MHz lowest frequency,
instead of 1200MHz before, when 800MHz was incorrectly reported invalid.
