No enabling reveal-mode did not worked for me either, that's why i
wrote "the only thing that could have worked better".

reveal-mode actually works, if you C-x o from the Ediff control panel
buffer to one of the source buffers and then back again. So it
probably has a check inside of it, that only reveals if buffer is the
active one.

Should be possible to do some magics with defadvice to make it happen
regardless if buffer is current or not, if buffer is part of Ediff
session or some other special condition.
