It wouldn't be all that hard ... we'd just need to add a new entry point
to the dmi codefor random to call (and a stub somewhere so that
CONFIG_DMI=n kernels still build). But getting some per-platform
data into the random pools earlier is a good thing ... it means that
users of random data will see the benefit earlier than they do now.

So add the big fat comment so that people know not to break this
useful (if not entirely intentional) functionality.
