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.
