    Hi,

    I'm just testing your IdleC1Halt patch (didn't reboot yet) with 2.6.4, but
    there is a problem if apm is enabled in the configuration:

    arch/i386/kernel/built-in.o(.text+0x10b65): In function `apm_cpu_idle':
    : undefined reference to `default_idle'

    Your patch sets default_idle() static, so its not available in apm.c file.

    Usually I compile with acpi and apm support to switch between both in case of
    an unsual problem, and I think many people also do so.
