I've tried it, but mesa-dri is required for xserver and it won't compile 
without it. libgles-omap3 cannot replace the mesa dependency, though I'm 
not sure  if it is a simple config issue or some interface is missing 
(libgl). And as libgles-omap3 also provides virtual/egl, the bitbake 
process detects, there exists multiple projects with the same provided 
feature:

NOTE: Resolving any missing task queue dependencies
NOTE: Preparing runqueue
ERROR: Multiple .bb files are due to be built which each provide 
virtual/egl 
(/home/gzp/work/gumstix/oe/oe-meta/meta-ti/recipes-graphics/libgles/libgles-omap3_4.05.00.03.bb 
/home/gzp/work/gumstix/oe/oe-core/meta/recipes-graphics/mesa/mesa-dri_8.0.4.bb).
  This usually means one provides something the other doesn't and should.
NOTE: Executing SetScene Tasks
NOTE: Executing RunQueue Tasks

(in local.conf: PREFERRED_PROVIDER_virtual/egl="libgles-omap3")
