On Ubuntu Jaunty, on my Acer Extensa 5620, the € and $ keys to the right and left of the up arrow key do report keycodes (435 for € and 434 for $) but they are non-functional in X. Xorg.0.log shows "(WW) AT Translated Set 2 keyboard: unable to handle keycode 435" and "(WW) AT Translated Set 2 keyboard: unable to handle keycode 434" when I press them.
