Make sure that you disable auto_negotiate=0 on the same line you are
specifying the line speed otherwise nothing will happen at all.

I'm not Michael Brown, but I hope it helps :-)

At least in Redhat (I don't know Debian at all) there are two drivers that
manage Broadcom cards: bcm5700 (from the manufacturer) and tg3 (open
source). Dell recommends bcm5700 driver, RedHat tg3, you choose.

And about the 100 Mbps:

1.- Do you have a network device (switch, hub, router, etc.) capable of
stablishing connection at that speed with the machine? Are your cables right
for that speed?

2.- Try mii-tool. I don't remember the exact sintax, but man mii-tool is
clear enough for setting up authomatic speed negotiation, or even forcing
speed (be carefull is the machine is remote, you can lost all comunications
with it!!!)
