The problem is not the user space programs, it's really if the newer kernel
will boot in your hardware.
If you use the RPi kernel, you can use the lasted kernel without problems,
but if you use the mainline kernel (Linus) you will have a few problems.
Just because it doesn't have all the modifications made on RPi kernel.

If you read this docs you are able to test different kernel versions
without problems. So go test it.
