9.0-BETA2 do not support SpeedStep on E5420

[K. Macy]

I was just discussing this issues with some others - evidently est(9)
works fine on both older and newer cpus. I see you're active on lkml -
does the linux driver work correctly on this machine? i.e. do you know
that it isn't disabled in the BIOS.

Thanks
