Log:
Integrate kbdmux(4) into syscons(4) and kbd code.
By default syscons(4) will look for the kbdmux(4) keyboard first, and then,
if not found, look for any keyboard.
Current kbd code is modified so if kbdmux(4) is the current keyboard, all
new keyboards are automatically added to the kbdmux(4).
Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at
the loader prompt, or at runtime, by kldload'ing the kbdmux module and
releasing current active keyboard.
If, for whatever reason, kbdmux(4) is not required/desired then just do
not load it and everything should work as before. It is also possible to
kldunload kbdmux at runtime and syscons(4) will automatically switch to
the first available keyboard.

Ultimately I would like to see this enabled by default so that
everything 'just works', but with a way to easily disable it in case
something goes wrong. Would that be possible?
right now i can think of two ways to make it enabled by default:
1) add 'device kbdmux' to the kernel config (or even make it required)
Could you add a check to the probe/attach routines of kbdmux so that it
could be disabled via a loader hint? I assume that there will only be
one instance of the kbdmux device, so this should be easy to do.
Something similar is possible with acpi, fwiw.
2) set kbdmux_load to "YES" somewhere in loader.* files (somewhat
similar to acpi).
Actually, acpi is much more evil. The loader probes the BIOS to see if
ACPI tables are present, and then sets the acpi_load variable based on
that. So no variables in loader.* are present in the default install.
If we wanted to add the kbdmux_load variable in the default system then
we will need to add /usr/src/sys/boot/forth/loader.conf, or add magic
to the installkernel target to handle it similar to device.hints.
with option (2) above it would be easy to disable, i.e. just do
unset kdbmux_load
at loader command prompt or loader.rc
thanks,
