since we don't have X now. I google about this. I don't know how to 
modify the console driver. can you tell me which file I need look 
into? thanks.

I found an another method. we use busybox in rootfs. the busybox have 
command [dumpkmap] [loadkmap] [showkey],

in host system run :
/usr/bin/dumpkeys > normal_keymap
/usr/bin/loadkeys funky_mini_keyboard_keymap
/usr/bin/busybox dumpkmap > funky_mini_keyboard_keymap.bin
/usr/bin/loadkeys normal_keymap

then in target system run
"loadkmap funky_mini_keyboard_keymap.bin"

in our device have a two special keys
[RED UP POINT] keycode is 94
[QI] keycode is 93

the loadkeys alwasy like:
compose '|' 's' to '$' 

how to write the keycode to the loadkeys file.

I just found this method yesterday. not test yet.
anyone have experience on this?

thanks for advice
