>Description:
When using X environment with USB JP106 keyboard, 
some special keys of JP106 are not able to input.
These keys always return keycode 8, this code is unused on Xserver.
Because these keys return the same code, cannot map a unique keysym with 
xmodmap.

This occurs on NetBSD/dreamcast, this JP-kbd has the same keycode with USB kbd.
>How-To-Repeat:
Connect JP106 Key to RPI and startx,
Change keyboard map to jp:
 setxkbmap -layout jp -keymap jp106
Input JP106 special key:
 '\|' (Left of Back Space on JP106)
 '\_' (Left of Right-Shift on JP106)
 Muhenkan (Left of SPACE BAR on JP106)
 Henkan (Right of SPACE BAR on JP106)
 KATAKANA-HIRAGANA (Right of Henkan on JP106, or Left of MENU/WIN)

Watch keycode with xev(1).


>Fix:
Patch for bsd_KbdMap.c for NetBSD/current.
See also usbmap[] of external/mit/xf86-input-keyboard/dist/src/sun_kbdMap.c. 
This patch is made into the same as sun_kbdMap.c.
