It would be very nice to get Mr. Daplas back.

My opinion (only) is that any subsystem that has lots of doc and/or kernel parameters should put that info into Documentation/<subdir>/, so adding to Documentation/fb/ is good. (sound is another big candidate for this. All of those "snd-xyz=" entries in kernel-parameters.txt don't actually help other than to say that there are some user-settable parameters that someone has to go search for.) We should probably also extend this entry in kernel-parameters.txt:
video= [FB] Frame buffer configuration See Documentation/fb/modedb.txt.
to point to Documentation/fb/ for all frame buffer docs.
