There is a generic DRM renderer plug-in that was committed containing non-driver/hardware specific code and then following that was initial support for NVIDIA, Intel, and AMD hardware with this DRM plug-in. Pressumably this plug-in will be used to provide a fancier boot process by leveraging more of the DRM capabilities of the hardware, or to at least speed up the process, but any Plymouth code that utilizes this has yet to be seen. Plymouth 0.8.0 was also tagged today in Git.
