Currently Power Attack isn't that good of a feat. The penalty to attack rolls doesn't balance the damage in most cases.
Here's an option to make power attack more useful, but in a limited number of cases. Note: Remember that basic attacks are technically powers, so the feat works with them as well.
Power Attack
Prereq: Str 13
You can make your most powerful attacks even stronger.
Benefit: When you use a power that has a single attack, and the attack deals at least 3[W] damage, increase the damage dealt by 1[W].
So this feat gives you a free bonus, no attack penalties just extra damage. But the damage only applies when you are using the big attacks. It also naturally scales between one handed and two handed weapons. A rogue doing 3[w] with a rapier might like this feat, but a barbarian using a mordenkrad gets even more damage.
I also like the fact that it makes the big single damage powers more useful. Right now powers that have lower W's but side effects, or powers that have multiple attacks are often better than a single big damaging power.
My only concern off hand is the Barbarian's Avalanche Strike. Its the only encounter power I know of that does 3[w] at low levels.
