The image is passed two arguments, a pointer to the tagged image header,
and a pointer to the bootp structure. The image header is needed for the
trampoline segment first-{linux,*dos}.S (in mknbi) to locate the
parameter string, among other things. You could drop support for
first-linux.S, but it would still be needed for first-*dos.S.

Don't worry, I'm a memory skinflint too. :-)
