Yes, we ship the eeprom utility for that.

Actually, all we need to know is the OF partition number for whatever  
we're going to load the kernel from. I'm not sure if ofwboot.xcf is  
clever enough to find the first ffs partition and use that if none is  
given. The only problem left is to teach the installer to distinguish  
between Old World and New World ROMs. Old World can't read HFS but can  
do the partition zero method, New World can read HFS but can't do  
partition zero. In theory all OF versions Apple ever shipped should be  
able to read FAT and ISO9660 though, even the ancient ones.
