It is a usable functionality (i.e. allows the driver to select which 
connectors or CRTCs is fbcon allowed to bind to) and I see value in it.
I am actually doing some work (not ready for public release yet, but will 
be in some relatively near future) that makes the use of this feature.

If you (and the rest of the community) would prefer to see the use case 
first before merging these two patches, I am perfectly fine with waiting 
(I'll resend later, after I show the use case), but I would not like to 
see the functionality killed only because drivers don't use it at present.

thanks,
