why only on X86?
PowerPC exports this data via the OpenFirmware so it already shows in the /sysfs entries. I was thinking to combine those sysfs entries under this code, but that is something in the future.

In regards to all other platforms, I figured I would only make it supported under platforms that have been tested. Is there anything that stops this from working for example of IA64? Well no. The hardware that supports the iBFT is either in the BIOS or in NICs - so the SGI or HP boxes _should_ work, however I am not comfortable to make it supported unless I've tested it.

It should, presumably, depend on ACPI, rather than on X86...?

Actually no. That /should/ be the correct answer, but none of the hardware vendors actually provide the table via ACPI yet. Also, if they did, the support for /sys/firmware/acpi/tables/* would be sufficient instead of having this code *at all*.
