estX still not attaching properly

hi there,

although i'm running a very recent current which has "ACPICA 20090521", estX
still isn't attaching properly on my machine:

est0: <Enhanced SpeedStep Frequency Control> on cpu0
est: CPU supports Enhanced Speedstep, but is not recognized.
est: cpu_vendor GenuineIntel, msr 925092506000925
device_attach: est0 attach returned 6
est1: <Enhanced SpeedStep Frequency Control> on cpu1
est: CPU supports Enhanced Speedstep, but is not recognized.
est: cpu_vendor GenuineIntel, msr 925092506000925
device_attach: est1 attach returned 6

here's the output of `sysctl -a|grep freq`:

this is my cpu:
