kbdmux(4) is pretty good for standard 102-104-keys keyboards found at
common desktops.

But it does not work that good with some laptop ones.

There are no "Flight mode on/off", "Touchpad on/off" e.t.c. events
defined in AT-keyset but they exist in evdev-keyset.

Unfortunately, we do not support keymap uploading in our drivers yet to
make utilization of this advantage easy

but IMO its better to switch to direct key-event reporting earlier
rather than later.
