2.4.20, tg3 , and 5704

Hi,

I got a preproduction Dell server with 2 5704 NICs
onboard. 2.4.20 w/tg3 doesn't want to work. When loaded
the link light on the switch just goes on-off-on-off ...
seeming like it is reinitializing all the time. 

I just did get the current Broadcom drivers sources and
it seems to work ok (ping and ftp works on 100Mb ...)
built against 2.4.20.

I prefer to use tg3 even though I have to backport
to 2.4.18 (not a big fan of the Broadcom code and
it's not part of linux).

thanks for any help
