What do you think is missing?  This is what gets reported on my laptop:

mode "1280x800"
    geometry 1280 800 1280 1024 32
    timings 0 0 0 0 0 0 0
    accel true
    rgba 8/16,8/8,8/0,0/0
endmode

DRM doesn't provide full information via fbdev - its fbdev is just a
compatibility later nothing more.
