Keith,

The rename is complete and correct and works as expected.

No, the way it is now is correct - it doesn't need to include ti-sgx-ddk-um in 
PROVIDES list, as that's already the name of the package. The reason it 
includes the old omap5-sgx-ddk-um-linux name is to ensure upgradeability path 
from the old name of the package.

Same as above. Moreover, adding own name into RREPLACES and RCONFLICTS would 
be problematic, as it would mean it replaces and conflicts with itself.

Now, as to your problem. Which exact platform are you trying it on? I see you 
mention beagleboard, so if it is really an old OMAP3-based BeagleBoard and not 
the new AM335x-based BeagleBone, then it simply is not supported. Currently 
supported platforms by the new SGX components are am335x/ti33x, am437x/am43x 
and j6/dra7xx/am57x:

http://git.ti.com/gitweb/?p=graphics/omap5-sgx-ddk-um-linux.git;a=tree;f=targetfs;h=76a04f848bfa75a7e157e5d1b14e518380f8ec70;hb=refs/heads/ti-img-sgx/1.14.3699939

For old OMAP3 platforms, you'd still need libgles-omap3, which, unfortunately, 
hasn't been updated to recent 4.x kernel and therefore was dropped in krogoth.
