Great job finding that regression. I wish the chameleon team would keep track of the latest stable version. I guess everyone should stay at <= 1107. Not aware of any important changes since then anyways, are you?
I eventually figured this out, and it is due to a bug in Chameleon. I described the cause in the Chameleon issue at http://forge.voodoop...eon/issues/123/. The problem occurs for versions of Chameleon after r1107. In the issue, I describe how you can fix it for more recent versions.
Hopefully apple will add more sandy bridge products and clean up their PCI match list in the process...
That's generally true, but the 2405S and 2500K have HD 3000. You can see that in the processors in bold at http://en.wikipedia....ktop_processors
