Are you talking about sdlfb or vncfb?

sdlfb works with scancodes and its mapping to Linux input layer
keycodes assumes a standard AT or PS/2 keyboard.

vncfb can't work with scancodes, because LibVNCServer doesn't provide
them.  It has to work with key symbols instead.  This can't work in
general, see the source code for why.  Its mapping to Linux keycodes
assumes you're using the usual US keymap.

Nobody coded it yet.  It would sure be useful.
