Is this at all related to this problem:

i.e. env not being copied from flash in relocate() when ENV_IS_EMBEDDED is set?
The effect is the same but the setting of ENV_IS_EMBEDDED is neither here nor there as I'm starting from a configuration file for the FADS board. This has only 8 sectors of 256k each so it makes no sense to embed the environment (wastes too much space) - the problem as you say is that it never gets copied out of Flash into RAM !!
I'm going to 'have a go' at cpu/mpc8xx/start.S to modify it for the FADS case but since I've never used ppc assembler before it may take a while!!
I think if I can identify where I get the source (presumably GOT(environment)) and destination (not found this yet) addresses and the length of the environment (I'll use the config define) at the assembler level then I'll be able to hack something together!!
Never will so few lines of code have taken so long to write :-))
