Excellent! :)

The GNU toolchain (gcc and binutils) in the FC system may be unable
to build LB correctly. Can you tell us what version of gcc and
binutils you were using in the FC system that produced bad results,
and what version you have used to produce a working result?

That depends on what the keyboard connects to. Is it a USB keyboard
or a PS/2 keyboard? Whatever it is, could you also try the other?
Also see Ron's question about which chip the keyboard is connected

Not always an application, but there are configuration files in most
if not all Linux distributions for setting up the keymap. That
doesn't help if the kernel can't see the keyboard however. Feel free
to send a serial port capture from a full boot with LB to the mailing
list, we'll look at it and see if we can find something pointing to
the error.
