    You mentioned on IRC that /sys/firmware/acpi/namespace didn't
    contain anything that looked like an IPMI device. Try dumping the
    actual DSDT and looking there -- I'm not sure everything makes it
    into /sys/firmware/acpi/...

    Use the latest "pmtools" from here:
    http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils

    and "iasl" to disassemble it.

    I did this on an Intel Tiger, and didn't see any "IPI" devices in the
    namespace either. I think it's a firmware bug if the hardware
    is there but not described in the namespace.

    So maybe you'd have to grub through SMBIOS to workaround
    the firmware defect.
