ABIT VT7 mainboard
>Description:
      All our FreeBSD systems are on USB KVMs and as long as no PS/2 keyboard was plugged into the mainboard, 5.2.1 and before would assign kbd0 to the first USB keyboard. That allowed the KVM keyboard to attach to the active machine. On 5.3-BETA2, kbd0 is apparently always assigned to the PS/2 keyboard, regardless of whether one is plugged in or not. This means that the first USB keyboard is assigned to kbd1 and the console is shut out after boot to the KVM.
>How-To-Repeat:
      Pull out the PS/2 keyboard and mouse connectors and attach a USB keyboard and mouse. On 5.2.1 and before you can type into the console after boot. Doesn't work on 5.3 BETA2.
