Well, there are two parts to it:
1) the user interface: for a user following hints from the internet
because their new machine blanks the screen at boot time the command
has to be as simple as possible. We may work around that by adding
the required magic to the standard boot menu on install media.
2) the implementation: a very simple and scalable implementation
(instead of the static list of known DRI devices, which IMO is not
that hard to maintain either) is a global kernel variable like
"drm_enabled" and all DRM related drivers checking for that in their
probe function.
