Thomas :

* 2.6.32.15 (Kernel Reference with functionnal cpufreq)
- Boot params : None

--> No /sys/devices/system/cpu/cpu0/cpufreq/bios_limit

* 2.6.36 (+ 4 Patches HW_COORD, SHARED_TYPE, HW_ALL, HW_STATISTICS)
- Boot params for patch 4 : acpi_cpufreq.disable_average=1
- Boot params : clocksource=hpet

# cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit
1199000

So, 1.20GHz.

Thank you. I will investigate on the BIOS/ACPI track.
