There is a remove_conflicting_framebuffers call which is already used
on x86 to remove e.g. efifb when a kms driver loads, the plan for
simplefb / arm is to do the same. That is where we stand now, we've
a plan but you're the first person to actually try this.

Note that you may want to use simpledrm by David Herrmann (added to the
Cc) instead of simplefb as that will give you a kms driver right from
the start, simpledrm is not yet upstream but should go upstream soon.

Regards,

Hans
