Yes, but it works better when using it. (most?) tg3 are able to work
without the firmware upload, but lack important features for a gigabit
card - IIRC, the main one was the ability to handle jumbo frames
(frames longer than what the original Ethernet standard allows, but
needed to have good performance with a gigabit bandwith).

I think we could even scrap the firmware for the kernel used for d-i -
A install will certainly not need to saturate a gigabit connection, it
will just be a bit slower, but nothing terrible. Maybe (I also don't
have access to a tg3 card) the firmware can be substituted for a stub,
even if the userland loader support is still not complete.
