I'm new to this list, and not sure if it is the right place to ask my 
question. Recently I prepared an additional keyboard layout for Creative 
wireless desktop 8000 for X (and posted to bug 3514) but 
there is one thing that makes me wonder. 
Are the keycodes for X limited to 255? (one byte) If not how to add keys with 
scancodes 278-280 (0x116-0x118) ? <linux/input.h> allows 9 bit keycodes (max 
0x1ff) this is the reason for my question, since in X, keys with scancodes 
>255 remain dead, trying to add (in xkb/keycodes/xfree86) additional 
scancodes and increasing maximum made all additional keys of the keyboard
