Okay so at least we know it's not specific to your switch, or
to auto-neg nor the cabling (two different switches + boxes with
the same problem probably isn't your fault.  :) ).  That's definitely
evidence that it's a driver problem, probably specific to the 5704
(since I have two machines using 5750s without this problem).

Looks like we'll need someone with the Broadcom data sheet for
the 5704 to help out.  There's also the Bill Paul <wpaul at windriver.com>
and David Christensen <davidch at broadcom.com> (who worked on bce(4),
but might know of some details here...)
