6 is lowest FSB multiplier, 0.266*6 = 1.6GHz -- your lowest.
7 is multiplier to get 1.86Ghz -- your max.
"power management: no" means power management is disabled.

also, the file cat /proc/acpi/processor/CPU1/info gives this
processor id: 0
acpi id: 1
bus mastering control: yes
power management: no
throttling control: yes

Is power management not available according to this file?
One more thing is that, only two frequency levels ( 1.86 and 1.6 Ghz)
are being used. This does not cause much power saving..
How many levels are actually available on core 2 duo?
I cant find any PSS in the DSDT dump.

support.
C1 is the only C-state supported on CoreDuo2.
PSS should give you P-states.
