Well, writing that email caused a shift in the universe and I was able to
find out the answer to my problem.  For anyone who might run into the same
problem, here is what was happening:
I was using a uClibc development environment from http://www.uclibc.org
because I wanted to compile everything against uClibc.  The development
environment uses busy box (http://www.busybox.net) for many of the basic
system utilities. One of which is gzip.  Because busybox was designed to
be small, it doesn't accept all of the commandline options that the full
verions does.  It jsut so happend that some of the flags it doesn't accept
are the flags that the kernel make file uses when you do a make bzImage. 
So I compiled the full version of gzip, did a make bzImage, and everything
works now (well, the kernel does at least :)  Thanks.
