In meta-yocto/conf/distro/poky.conf there's a line which sets:

PREFERRED_VERSION_linux-yocto ?= "2.6.37+git%"

Which is then overridden for the qemu machines to:

PREFERRED_VERSION_linux-yocto_qemuppc ?= "3.0%"

If you add a similar line for beagleboard to a conf file, such as 
local.conf, it would look for a 3.0 kernel version and use your tree.

PREFERRED_VERSION_linux-yocto_beagleboard ?= "3.0%"

I know you've switched to master but I wanted to help you understand the 
system is doing what it is.

Cheers,
Joshua
