Im having similar issues with iBook and Finnish keybord. Last time I checked, there was no public tool to create keymaps.

Other issues Im having, iBook is running constantly at 50C and the wrist area is uncomfortably hot. Touchpad is not working, I have to use ShiftClick. Keeping the modifier down when clicking menu item do nothing. I have to release the modifier before clicking.

Panels deadlock the system with 100% cpu when double clicking the zipping button. Dragging panels to last position in ambient prefs it not working. Speaking of Ambient prefs, "Get from window" window setting is still not workin. I think I reported that bug 2 releases ago.
