What about applications compiled with GTK+ target linux-fb or similar toolsets?
If I understand it right only the fbcon layer should be used (if possible) to be
on the save side.

Okay I'm not so much interested in Xfbdev than in fbcon. Can you transferred
your code to the generic part as Geert Uytterhoeven already asked. I could help
