help understanding payment module with order total to 0

[blackhawk]

Is there anyway we can skip the payment method selection on checkout if....

-The items(s) in cart are freeship
-The total order in the cart it totaled to $0.00
-Download is enabled from the admin
-And product weight cart is 0

?

The reason I am asking is because I am forced to select a payment method with single page checkout, when my total is 0.00 dollars.

If I only use Pay Pal at my payment module, it will not go through anyway because total is 0 and pay pal doesn't like that.

Also with one page checkout, I can't use check/money order module it total in cart is 0.00 dollars. I'm assuming that is also normal behavior.
