Because there are very good reasons for having a firmware seperate from
the OS.  Otherwise, you're more or less proposing a new run-time-environment
that has to do all the hardware sanitizations and initializations before we
get to the bootstrap environment.  That's going to be so system-specific and
disparate from the kernel that it doesn't, IMHO, make any sense to put it
there.  This is especially true since *not* having it in the kernel gives you
the chance to exploit the same firmware environment for non-linux OS'es.
