User (adding EZ, sorry for missing you out on initial post)
claims that cpuid shows:
So I ran the cpuid commend and it returned:
Thermal and Power Management Features (6):
      digital thermometer                     = true
      Intel Turbo Boost Technology            = true
 ...

Not sure whether this really is the same bit and whether this is prove that 
IDA feature bit has been switched by Linux OS (by SMI/firmware?) after 
initializing?

IDA cpufeature bit is not set in /proc/cpuinfo

EZ probably can do the one or other msr read/write if you need someone tests.

Good luck,

         Thomas
