A friend from another forum had a copy of ati stream sdk 2.1, and I was finally able to get OpenCL enabled on this HD4670. Using Catalyst 10.7 along side it.
So now CGminer sees it.

But, CG miner keeps giving assorted and vague cl errors and reporting it can't initialize the GPU. I've tried over a dozen versions of CGminer from 1.1.1 through 3.7.2, and every version gives different errors. As does different switches.

Is there a prefered cgminer version for older driver sets/cards? Are there any particular switches and values that this card needs?
