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.
