Please don't do that (the DTB append that is).  This is a convenience 
for platform where it is impossible to update the bootloader in order 
to accommodate a DTB.  A Pandaboard certainly does not fall into that 
category.

And this DTB append is not something I'd advise Fedora to ever support 
unless there is absolutely no other way.  Most of the Fedora ARM targets 
should have other ways.

U-Boot has had native device tree on ARM for quite a while now.  Please 
ensure that the U-Boot version on your Panda is sufficiently recent.
