June 8, 2011 - Progress.
The O2 sensors have now reported for duty. It's quite possible that one of them was incorrectly diagnosed as wrong, thanks to some confusion on my part between Bank 2 Sensor 1 and Bank 1 Sensor 2 in my logging program. Possible, but not certain! Regardless, I can read them both happily now.
Unfortunately, that hasn't solved the problem. The sensors are displaying what I can feel - the car is going lean for 15-20 seconds, then rich for 15-20 seconds. One interesting thing is that the car still isn't going into closed loop as far as I can tell. I haven't spotted the problem in the datalogs yet, but I'll get there.
