Note: this is against 6.1.98, the snapshot from Saturday 4th. Choosing Norwegian keyboard in the GUI install doesn't succeed - take a look at the VC after trying to do it. No Norwegian characters can be entered, the keyboard layout is unchanged. The result after boot is OK in X (not during the install), and badly broken in text mode (as entered in another bug).
Will be fixed in the next cut of the installer. Actually have seen it working here in the lab.
