Why would you use the old device tree on the new kernel?  The
8349EMDS is in mainline IIRC, and hence you aren't tied to the
old dts file.

What is the u-boot version?

How much difference in size is there between the two uImage?

Does the 3.x image work if you turn off some stuff to reduce
the size?  (you can turn off essentially all device drivers
other than serial for this test)

What happens if you take a default yocto mpc8315 BSP, and enable
the mpc8349EMDS in that kernel config (one kernel can support
multiple mpc83xx boards, IIRC -- haven't booted one for a while...)
