In other words, being able to drop PS2 keyboard/mouse for USB, but still supporting legacy software via SMM. This doesn't seem worth the effort by a long shot. Another take on removing PS2 sounds more interesting to me: a legacy-free PC qemu hardware skew, with a legacy-free firmware (OVMF :) and only supporting legacy-free compatible OS's. -Jordan
