To me, this happens as well, using Lucid Lynx 64 bit. Even if the PS/2-keyboard is unplugged, the key which decided to get stuck keeps repeating.
What I would like to point out: It only happens when tpying in forms displayed of Firefox (so NOT during any other application of Ubuntu), and then there on certain forms: when trying to write an email in Outlook 2010 webmail, or when writing a comment on the launchpad page, the key repeating error almost reroducably happens.(This is why I needed to write this mail in Gedit and copy it conscutively into launchpad). On the contrary, it does e.g. not happen in GMail - so maybe there is an interference between some applications and firefox and Ubuntu. Despite I turned off the repetition in the preferences -> Keyboard settings -> General -> Repeat keystrokes when being pressed, the keyboard keeps stuck in the Firefox forms as mentioned above.
