I don't understand how this was allowed. Because when I try this
with a 2.6.18 tree.. (nothing changed between -rc7 and final for cpufreq)

<editted a .config to match your config>

$ grep ACPI_PROCESSOR .config
CONFIG_ACPI_PROCESSOR=m
$ grep POWERNOW_K8 .config
CONFIG_X86_POWERNOW_K8=y
CONFIG_X86_POWERNOW_K8_ACPI=y

and then after a make oldconfig the CONFIG_X86_POWERNOW_K8_ACPI is removed
as it isn't valid.

Did you edit your .config by hand ?
