BTW, I am wondering if it would be possible to write a DRM emulation
layer on top of (basic, e.g. no MMIO, just fb) fbdev?

That exists, sort of.  I first posted it here:

   https://patchwork.freedesktop.org/series/58569/

and it has later been transformed into these conversion helpers that I 
have somewhere on gitlab.

Best regards
