Jakub - I'm CCing you to get an answer to a question about tilo near
the end of this message.

Ok, I'm working on a 2.2.1 kernel right now (I'll probably have to
tune the options a bit to get the size down).

I had to patch the source to get RARP/BOOTP in the Ultra kernel.  (The
startup code wanted access to a variable in the ipconfig.c module.)

Does this happen with tilo too?  The only limits I see in the source
code are:

   "rootlen + sun4c_size + 0x4000 + 0x10000 < 0x330000"
   "rootlen + sun4u_size + 0x4000 + 0x10000 < 0x330000"

And a max size for the final file of 0x400000.

Ultra kernels are typically >2MB. I doubt I can get them under 1.5MB.
