I don't understand why the kernel needs to be linked to the distro. I use Gentoo and kernel upgrades are orthogonal to my userspace because of Linus' "we don't break userspace" policy. I do not even need to recompile packages when I change my kernel.
If EAC signs a custom kernel I will just boot into that one when I want to play video games. Unlike dual-booting Windows it won't delete my Linux boot entries and I can use all my applications.
