I built 2.6.18 and booted into it with cpufreq.debug=3, and got not a
squeak out of it.  There's no cpufreq-related info in /var/log/messages
at all.

I'm using the Fedora kernel config, which builds acpi-cpufreq as a
module and speedstep-centrino built-in, but no joy.

I'll try building the lot as modules, and see how that goes.

Here's what's in my .config with the setup that prints nothing at all:

CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
CONFIG_CPU_FREQ_DEBUG=y
CONFIG_CPU_FREQ_STAT=m
CONFIG_CPU_FREQ_STAT_DETAILS=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m
CONFIG_X86_POWERNOW_K8=y
CONFIG_X86_POWERNOW_K8_ACPI=y
CONFIG_X86_SPEEDSTEP_CENTRINO=y
CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI=y
CONFIG_X86_ACPI_CPUFREQ=m
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
