'setkeycodes' can do that.

Not yet, but I'll have to write one.

X needs to be set up as well. In 2.6, X doesn't get real raw codes but
instead simulated raw codes generated by the kernel.

The formula for setkeycodes is:
if (code > 0x100)
you're out of luck, setkeycodes doesn't handle this yet;
else if (code > 0x80)
result = code - 0x80 + 0xe000;
else
result = code;
And then you use 'setkeycodes result keycode',
where keycode you find in include/linux/input.h.
