I just tested the Kubuntu Feisty Herd3 cd (amd64) on my M1210 and there were no lock-ups, I used no extra kernel boot parameters. However when i closed the lid and reopened it the screen wouldn't turn back on, so i pressed ctrl-alt-f1 to get a console and pressed ctrl-alt-del to reboot. I'm currently running the i386 flavor of Kubuntu Feisty, and have never had any problem with the screen not turning back on. However this may be a completely different bug.
