Thanks. I see. Keycode in the kernel should be unified.
I'll use newer kbd utility (kbd-1.08) and rewrite keymap like below.
keycode 124 = backslash bar #Compatibility for 2.4 (for a while)
keycode 183 = backslash bar

BTW. I've extracted japanese keyboard specification from OADG's documents.
About OADG, please visit http://www.oadg.org/.
I attach those files. Usefull?
