Re: "There remains the (relatively) large supply of 733 parts, and the apparent severe shortfall at 800. I suppose this is an indication that demand spikes at the high end rather than tapering off, despite the higher prices charged at the high end. (in contrast to what I would guess is a bell shaped speed distribution coming out of the production process)."

Exactly - and the center of the distribution for the initial stepping was around 790MHz (no guardband included). To ship 733MHz, you need at least 821MHz assuming 12% guardband. To ship 800MHz you need 896MHz assuming 12% guardband. So if the distribution is near Gaussian with a 3 sigma distribution of +/- 15%, you ship lots of 733s but few 800s. There is no mystery here. At least for most of the wafer starts in the initial stepping, they simply did not have a high enough center target(or they missed it low) to ship significant numbers of 800MHz parts. They could have, but they didn't. They blew it. Intel screwed up. It happens.
