There is a third stage bootloader program that is included in a
tagged image by mk{nbi,elf}-linux. That is where the option processing
currently happens, I believe. The size restrictions are more relaxed
on this than on Etherboot (with a little effort, you can easily get
64KB to run it in.)
I would suggest modifying first32.c or adding a new implementation that
does what you need.
