Description of problem:
Arm/aarch64 disk images are missing cma allocation in kargs, which causes graphical issues on some hardware.
Version-Release number of selected component (if applicable):
Latest nightlies in F34
Adding cma=192MB to kargs fixes the issue.
Proposing as a Freeze Exception for F34, this affects some of our supported hardware when running graphical images.
Discussed here: 
Agreed to classify this bug as an "AcceptedFreezeException (Beta)".
I don't see a PR for this, unless I'm missing something?
