I must say I'm very puzzled how it is working correctly, unless the QEMU
instance you connected virt-viewer to had the '-k' option set with a
keymap. I've looked at the XQuartz code now and it has its own native
keyboard driver, and the hardware keycode I believe we'd get is using
the Apple virtual keycode mappings which is nothing like the xfree86 or
evdev mappings. On the plus side I know understand our key handling code
much better than I did before :-)
