Ubuntu Dapper and new mainboards

Today I was encountering a small “bug” under Ubuntu Dapper: After getting my laptop back from the IBM Repair center (I had an issue with the graphic card) everything was running as before, except one thing: I didn’t get an IP address from my router. I got an error when ifupping eth0:

SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device

After googling, I found the problem: I guess the mainboard got replaced by the repair center and thus I had an other MAC address. Strangely Ubuntu gets quite confused by such a change! The solution was to replace the old MAC address in /etc/iftab by the new one and reboot the system.
