jb, thanks for the info on drip edge vents. They may be the best solution. I'll take a closer look at them.
It seems that the drip edge vents also require a bit of carpentry and they have their own set of drawbacks. See below. I like your approach of ripping the fascia rather than ripping the sheathing as recommended by the manufacturer. --Billy

In existing homes, installation begins with cutting existing roof sheathing back three-quarters to one inch from where it meets the fascia. The ventilation and drip-edge system fits over the gap and is nailed to the roof sheathing and fascia board with standard roofing nails. As in all roof construction, attic insulation should not lie against the underside of the roof sheathing and block airflow once the system is installed. Roof shingles are then applied over the drip-edge portion of the system with a half to three-quarters inch overhang on the shingle starter course. The combination ventilation and drip-edge does not affect gutter installation.
Systems that place intake vents directly over the gutter may not operate properly when gutters are overflowing with ice, snow, or leaves. Additionally, the fascia board commonly supports the lower edge of the roof sheathing. Holding roof sheathing back from the fascia will increase the amount of roof sheathing flex along the drip edge.
