No need to send v5, done!

I have a system that appears to be affected by this bug:

  kepler:~> lscpu | grep -i mhz
  CPU MHz:                         4000.000
  CPU max MHz:                     7140.6250
  CPU min MHz:                     2200.0000

So I should be able to confirm after a reboot.
'CPU max Mhz' seems to be saner now:

  kepler:~> lscpu | grep -i mhz

  CPU MHz:                         2200.000
  CPU max MHz:                     4917.9678
  CPU min MHz:                     2200.0000
Yes, happy to know this :-)

Thanks,
Ray
