Otherwise it'll simply ignore the hardware entirely. By the looks of it
their keyboard probing is also somewhat different to ours, but that's
probably another story.

Well, I'd hate to lose the keyboard hotplug capability, but at the same
time, it _is_ 2010, and while I have personally used it historically, I
don't really foresee ever using it again.

this is actually fairly common in datacenter environments where people plug in crash carts to problem machines.

yes, everything has USB ports, so they could use USB keyboards, but it's actually pretty common to still use PS/2 keyboards (and while the systems all support USB, it's not uncommon to have KVM systems, including pretty expensive 'enterprise' KVM systems that still require PS/2 keyboards be used to plug into the KVM, so those are the keyboards that are in the datacenter that someone will grab to plug into a problem machine)
