[v+cpufreq]

You are probably getting a ton of these, but I did try to search google,
lkml, cpufreq-git and this mailing list and came up with nothing. So perhaps
you can point me to right direction, or ack that Core2 is not (yet)
supported?


So basically I have a Intel Core2 CPU T6600:

Motherboard is Asus P5B (i965).
   
Cpufreq enabled in config:
   
   # CPUFreq processor drivers

   CONFIG_X86_ACPI_CPUFREQ=m
   # CONFIG_X86_POWERNOW_K6 is not set

Kernel is 2.6.18-rc7 from kernel.org
   
SpeedStep set to "Automatic" in bios (no "on" option"), PECI "Enabled."

Still, I only get "Unknown p4-clockmod-capable CPU." during boot, and
cpufreq-info reports
