My personal preference is not to depend on this type of magic. The fix
I posted is really impossible to fail, and we want to guarantee no
failure in this important case.

Stefan's comment about not doing stupid brute force is a good point. I
am at fault for putting that in, but I did that because in the early
days there were bugs in linuxbios LAR parsing code ... we need to take
out the brute force.
