The loops are usually located near the bottom portion of the pack. The ice axe shaft slides through the loop, flip it up, then strap it to the pack. There is only webbing located on the side of the pack. I'll figure something out.
I checked out the military packs from Kifaru and the ice axe attachment, but unfortunatley the Timberline model packs only have webbing on the sides of the pack and hip belt. I have some extra cord I'll rig something up.
