Do the Avalon chips have the ability to adjust clock frequency / core voltage / etc?

I may make a fork(does that make sense for hardware?) of the board that adds the ability to do that.

It wouldn't be needed for a standard board but it'd be interesting to add

* Thermal sensors near each ASIC or heatsink that feed back over USB.
* Ability to adjust core voltage (probably by hand)
* Ability to adjust frequency (maybe digitally with a DDS, - really need the Avalon design docs to figure the best way to do this)

Edit : We will need to make sure the decoupling and board step down regulator is capable of driving 16 chips.  it looks like the standard avalon board only runs 10 chips per VRM.  Just really need the documentation from Avalon
