We should make sure that the system allows for this, but not go and
implement it like this by default. In the cases where we _need_ to be
up and running to point X in Y seconds, you do need to do things
slightly differently. You can make sure that things are cleared, MMU is
off, et al. What I've sort-of been thinking of for PPCBoot applies to
this case as well. We'd have a 'wrapper' which basically converts a
bd_t if existing (since we will probably want to do this anyhow, PPCBoot
or not), and make up bi_recs for things like CONFIG_CMDLINE, if given.
Then, if needed (compile time) uncompress and jump.
