God, I don't think its my problem any more! I created a sparc boot 
floppy image using dd(1) with the image I got from:

http://mirror.israel.net/pub/redhat/linux/4.2/en/os/sparc/images/boot.img

This image, said should be able to boot, still produce the above error 
in OBP. I also googled around, lots of people are asking the same 
question (why cannot boot from floppy) and given no satisfying answer. 
Perhaps this is an UltraSparc problem
