I see it advertised on the CS1504 the ability to turn off timestamp in order to store more data. Do you have any idea how to accomplish this? I’m assuming it has to be scripted as a command to the device, but I am not familiar with it or the SDK.

And I’d guess that the general population on Flickr is substantially low end on average, so the users and cameras both would tend to shy away from high-ISO stuff… it’s just not high enough quality. However, if you were to inspect a less-general population on Flickr (say, a D3 or 5DmkII group), the high-ISO stuff would be relied upon more, and of a better quality, to appear more. But (generally speaking) Flickr is not the first choice for higher-end photo display… it’s great for its community aspects, but it’s not an aesthetic place to view art.

So, I think your sample perhaps underreports to a great deal; if folks (point-n-shooters and pros alike) could get great shots of a kid lit by the candles of a birthday cake, you’d see a lot of those kind of high-ISO shots, but since only high-end cameras can do it now, you see few.
