Georgia on my mind

In recent days, we’ve stopped hearing much, if anything about the pseudowar in Georgia. Before Juno MacGuff became center of the media universe, the news seemed to be talking about diplomacy, official actions and reactions of national governments, and troop movements. In the dozen or so articles I’ve read in various publications since the conflict escalated a month ago, I’ve seen little discussion of the petroleum industry and virtually no mention of the Russian state-owned gas company Gazprom or the several oil and gas pipeline segments that cross Georgia. This has gotten a little better recently.
For readers unfamiliar with this contentious little piece of the world, Azerbaijan and the former Soviet republic of Georgia happen to be situated in such a way as to allow for the transport of oil and gas from the productive Caspian Sea region to the Black Sea, a major transportation hub to Europe and a petroleum source in its own right. For those who don’t know Caucasian geography nor have a map in front of them, this corridor snubs Russia and its massive gas industry that supplies much of Europe. (A primer on energy in the Causasus region, if you're so inclined)
With this in mind, I put some questions to the reader:
Why is Russia supporting the break-up of Georgia? Is Russian support for the break up of Georgia at all similar to the US overthrow of Saddam Hussein? Is Russian support for an independent South Ossetia materially different from US support for a semi-autonomous Kurdestan? Would anyone care what was going on in Georgia or Iraq, if these countries’ major industries were fruits, nuts, hand-woven rugs, and wool?
