John, you were close.  Here's an example from my local.conf:

PREFERRED_VERSION_linux-wandboard = "3.10.17"
SRCBRANCH_pn-linux-wandboard = "wandboard_imx_3.10.17_1.0.0_beta_test"
SRCREV_pn-linux-wandboard = "4299c87fd4d46fd786d1600c57986b1fe164138a"

You may want to double-check if your SRCBRANCH override really did work as you
expected.  I think you need the "_pn-".
