Support for the Tornado cards exists in the 3c59x driver for over a year.

If your 905C card is manufactured recently, chances are that is in fact a
905CX (notice "X" after "C"); the older drivers would not operate
correctly on these cards, receiving packets not being possible - so
ping-ing would not get any response from the network. The newer drivers
(in 2.2.19 and 2.4.3) have some fixes.

How did you get the 3c90x driver with Debian ? I was not aware that they
include it in the standard kernel... If you downloaded it from 3Com's
site (and still want to use it, in spite of newer 3c59x also working), you
should recompile it, not use the pre-compiled modules that 3Com offers.

That supports my ideea of a 905CX card...

This is not an IP-related problem, so don't do this again!
