Thanks so much, that explains it

in the other hand, vanilla ethertool-1.7 refused to show -S information and 
crashed the machine using -d

[root@discreto sbin]# ./ethtool -i eth1
driver: tg3
version: 1.2
firmware-version:
bus-info: 00:0b.0

that is a 2.4.20 kernel, the card is an 3Com 906B-T pluged in a 32bit/33Mhz/
5Volt PCI Bus.

I have reported this to the gkernel project on sourceforge
