Thanks Josh,

This is the sort of dependency I was looking for. Knowing this, I 
suppose the best thing to do is rename linux-linaro-2.6.35_git to 
linux-linaro-stable_git. I don't particularly care for this approach as 
"stable" is sure to change to a different version in the future - but 
then again, perhaps this is inline with Poky's goals of having a single 
known-good version of a package.

I'll work on updating this upon my return.

Thanks again for the info! While I can find things like the above, I'm 
not yet confident enough to affirmatively attribute them to the failures 
I was seeing.
