So, question: is there a reason why we can't enable both the USB keyboard and a native PS/2 keyboard with syscons? It seems that I frequently find myself in a position where I'd like to plug in a keyboard, or switch KVM choices to a machine, and discover myself with no access to the hardware console, and I know at least one person who uses FreeBSD in production and finds this to be a serious impediment (as it requires the system to be rebooted to regain console access, and when you have 8 machines per KVM, and you boot them all, switching back and forth to catch each probe is effectively impossible). Presumably our syscons is intended to select on source of I/O and use it, but it might be worth considering a change here.
