It looks like all you did was to define the string "linux-3.9-at91" in
its own variable, put that in your SRC_URI string, and remove the
"tag=..." field. Would your original recipe have worked if all you did
was remove the "tag=..." field?

Is KBRANCH being used somewhere else? Doesn't bitbake's "git" fetcher
already have a generic way of specifying a branch? Why would a kernel
recipe need to also define a branch variable? Do non-kernel recipes
also need to define some kind of branch variable too?
