Put batman.fth in /home/olpc and try "fload nand:\home\olpc\batman.fth".

nand:\ at the ok prompt is not / in linux, check with "dir nand:\" at 
the ok prompt.

Try to reset the battery with "1w-init bat-set-low" and "bat-recover", I 
have seen a battery with the see-bstate problem working afterwards.

Good luck.
