I got this from a AVR seminar.

Basically, you can do more then the bit count (8) if you can put
them back to back across certain pins.... i.e. don't reference
them to ground/vcc but reference them across pins.

If you need all 10 on at once, your going to have to multiplex
them....might be messy but should be doable.
