I don't know what size constraints the bootloader has to have
but the smallest two lisp interpreters I have found are:
$ cd /usr/ports/lang/slisp/work/slisp-1.2/src
$ size slisp
text data bss dec hex filename
17872 616 3584 22072 5638 slisp
$ wc *.h *.c
67 321 2266 extern.h

287 832 6358 object.c

slisp has most of the common lisp constructs.
$ cd ~/lang/Scheme/tinyscm-1.27
$ size scheme
text data bss dec hex filename
61342 4476 3480 69298 10eb2 scheme

Tinyscheme is a mostly complete R5RS Scheme (R5RS is the
closest thing to a Scheme standard) -- everything except
complex and rational number types, bignums, hygenic macros
and call-with-values and unwind-protect. You can probably
subset it quite a bit to make it far smaller (e.g. the real
number type and advanced math functions to avoid linking in
libm). If it matters to you, it has a BSD style licence.
