In single-user mode, you will be able to use the PS/2 keyboard.  This
change effects systems where there is a system keyboard and then a USB
keyboard is plugged in.  When the USB keyboard is plugged in, it will
become the console keyboard.  When it is removed, the first keyboard is
set back to the console keyboard.  The logic isn't perfect, but it
should work for any case you're likely to see in the real world.  The
"test -c /dev/kbd1" insures that this won't cause weird problems with
legacy free systems.

The issue I'm seeing is that with the PS/2 keyboard is always being
picked up, my USB keyboard works as a legacy keyboard before the kernel
boots, but during boot, the controller seems to switch out of legacy mode
and the USB keyboard stops working except natively.  I my poorly informed
theory is that something about the hack my BIOS uses to make legacy OSes
work was broken with Alfred's flags change.  It's entirely possible
this is a perversion of my particular BIOS or something wonky with
the hardware (HP OmniBook 500) but wanting to plug a USB keyboard into
a server after boot isn't that weird and this is pretty much the same
case.
