About irqbalancing:

Generally it is suggested to balance IRQs across all available CPUs for performance reasons.

I think the reason powertop suggests turning it off is when you have two real CPUs or cores, balancing IRQs can prohibit an otherwise idle CPU from entering deep powersaving states.

Not sure what the situation is in HT setups like the Eee (Atom) but I don't think it can matter there power-saving-wise.
