only crt0.S and init.o? Are they really that big? What about packing a really silent LinuxBIOS image without payload in 32k again? I remember some mainboards allowed that. Say I want a system with a flash utility in fallback (so FALLBACK_SIZE would be 64k) and the real payload in normal, so I'd want 448k for that.

I'd rather want a smaller Fallback than a smaller normal. Fallback is thought of as a recovery thing only. > anyway, you can set ROM_IMAGE_SIZE to any size > 1. >64K > 2.
