Is this what you are looking for?
http://arago-project.org/git/?p=meta-arago.git;a=blob;f=meta-arago-distro/recipes-graphics/wayland/weston/0001-udev-seat-restrict-udev-enumeration-to-card0.patch;hb=HEAD

BTW, you don't need mesa at all, just libgbm, but it requires some massaging 
with PREFERRED_PROVIDERs and bbappends to get it going for now, although 
there's been some discussion to get it fixed upstream in the future...
