Thanks to you guys, I have now created a more functional norwegian 
keyboard layout for my Kohjinsha SH6 with a japanese keyboard.  Here's 
the result:

I have created the file /etc/X11/xkb/symbols/no_jp with the following 
content:

xkb_symbols "basic" {
   include "no(basic)"
   name[Group1]="Norway - japanese keyboard";

   // apostrophe and asterix on Enter's lower left
   key <AC12> {[ apostrophe, asterisk, dead_doubleacute, multiply ]};

   // less and greater left of arrow up
   key <AB11> {[ less, greater, guillemotleft, guillemotright ]};

   // AltGr on Space's right side
   key <XFER> {
     type[Group1]="ONE_LEVEL",
     symbols[Group1] = [ ISO_Level3_Shift ]
   };
};

In xorg.conf, I've set XkbModel to jp106 and XkbLayout to no_jp.  That's 
it, no more xmodmap for me!

Best regards,
Henrik
