If you use the kernel config file below along
with bzip2 compression, I think you can fit everything
inside 160kb.

g% strip < 9tiny | bzip2 -9 | wc -c
 136003
g% strip < /sys/src/cmd/bzip2/8.bunzip2lite | wc -c
  18928
g% 

That leaves 5000 bytes to do load-related stuff
like jumping to the right address.  If you meant
160*1024 bytes, you've got almost 9000 bytes left.
That and bunzip2lite can be made smaller yet.
It is way too long and ugly to post,
but if you're interested mail me.  Basically
I took the bunzip2 code and replaced a bunch
of macros with functions to get the code size
down.  There's still plenty of room for improvement.
