I just started my Intrepid desktop without having xorg-input-kbd and xorg-input-mouse installed, which means that X.org in Intrepid now uses evdev for all input handling. This is nice, since it moves all input drivers out of X and uses the kernel input event interface instead – less code duplication yay!
By the way; evdev was one of the many things which made the EEE PC at linux plumbers boot in 5 seconds.
