Those are the nodes needed to used the devices, It looks to me like your distribution doesn't have the event interface modules built in.
My kernel config has this in it.
# Input device support
# Userland interfaces
Those nodes will also only appear when you have a device plugged in, but with the right modules, even just a mouse/keyboard will count and create /dev/input/event* nodes
Unfortunatly your distribution doesn't seem to have much info online that people who don't have it can get at. You'll have to register your product and ask on there unless you are familiar with kernel building.
