building new kernel failed

device        rl        # RealTek 8129/8139


But no device miibus as the notes say there must be.

Of course, once you get past this one, there may be more errors.  If 
there are, can I suggest that you first go back to the GENERIC kernel 
and start again, this time being a bit more conservative about taking 
things out.

You should also make a copy of GENERIC called something else.  Your 
kernel is simply not GENERIC any more, and may get overwritten by the 
real GENERIC when you cvsup.  From the file it looks like you are 
editing GENERIC in place which is a very bad idea and definitely not 
what the handbook recommends.
