vorsicht! there's a lot of magic stuff in the rtc. and where the magic
bits are depends on your particular special bios. i think the problem
is no one has pieced together 50-odd bytes from rtc - union(used bits).
i know that some folks have a dedicated aoe network using seperate
interfaces. if you have something like that and you think it's secure
enough, it can be used to store nvram.
