I have a AMD Athlon 64 x2 Dual-core laptop, Nvidia GeForce 7000M and Nforce-MCP67 and running Debian Lenny x86_64.
I had been facing the issue documented here http://forums.debian.net/viewtopic.php?t=14331&highlight=forcedeth but the solutions did not work and on last count Eth showed eth82.
The solution to this is to add the line
SUBSYSTEM=="net", DRIVERS=="forcedeth", NAME="eth0"
I just wanted to document this.
