And I think it is somehow related to fglrx. On Karmic+fglrx I had to add "noapic" option to grub and as a result notify-osd worked great. On Lucid+open-source ati I didn't have to do nothing - it worked out-of-the-box. However on Lucid+fglrx, adding "noapic" hasn't changed anything. It's broken on my lucid machine SINCE I installed the fglrx driver.
