Every kernel I've ever worked on has this problem. At some point, you
can print. Before that point, you can not. The simplest way to handle
the problem is to make sure people don't call any print functions
before it is possible to do it.

My experience has been that the way we're doing it can cause trouble,
because people end up calling print functions that never print
