We want a class device so the drivers can expose some informations like the monitor probing data (EDID), allowed modes list etc... to userland.
I now have access to these infos in some drivers like radeonfb that do full monitor probing, and the fbdev "API" provides no way to get that down to userland (for use by xserver or MOL for example). I could just add some cases to the existing ioctl API, but I don't like that ;)
