We've changed the setting for the port on which my sungem g5 is connected to "desired" on both send and receive, and it now advertises flow control on both, and sungem does pick it up properly. So it's indeed the default setting of those cisco switches that seem to not quite match what drivers like sungem or tg3 like. Ben.
