Evdev (dev/input/eventX) is the new way of communicating input events
to userspace. It allows input devices pass much more precise information
about their state and it is quite extensible. There are patches for XFree86
and X.org that evdev-ify X mouse and keyboard driver. I will try Google
for them later. They are pretty new, SuSE 8.2 would not have them.
Mousedev is a legacy interface and is very inflexible. I mean there are mice
with more than 5 muttons, many wheels etc etc; data that is impossible to fit
into PS/2 procotol. Look for example at wacom or synaptics drivers to see what
kind of information can be passed through evdev.
