That's different things. ofwboot lives in a ffs filesystem and is loaded by bootxx when using the partition zero method ( sd@0:0 ), ofwboot.xcf is loaded by OF from a iso9660 or MSDOS filesystem ( sd@something:,\OFWBOOT.XCF ), the two aren't interchangeable which gave me some headache because installboot with ofwboot.xcf doesn't complain but leaves the disk unbootable.
So, I couldn't get ofwboot to work on anything besides target 0 while ofwboot.xcf works from almost anywhere as long as OF can see the partition.

have fun
