Still resolved. Filled with 5 quarts (just hits the top line on the dipstick). I did about an hour of mixed driving with a few hard curves today and didn't see the oil light come on except for the ordinary momentary time it's on after starting it cold.
The moral of the story: In the stock setup, the pickup has to touch the bottom of the pan. Otherwise, you may momentarily lose pressure when the oil sloshes around.
