After some tests, "pre-down false" is not a workaround for me. I still have the problem even though ifupdown is not bringing down the interface. The computer is deaf to wake on lan magic packet after ubuntu shutdown.
I therefore suspect thet ifupdown may not be the (only) package concerned.
FYI, everything was working properly under Edgy. Problem appeared for me after upgrading to Feisty.
