 Ouch, I think I see where the problem comes from.
 That path is apparently never taken if the console is explicitly set =20
 to another fb or a tty since in that case OF doesn't setup the =20
 graphics hardware and drivers abort much earlier, which is why I never =20=
 
 saw it. In your case OF sets it up, then decides it doesn't have a =20
 keyboard and switches to ttya. I'll fix that, there's probably a bunch =20=
 
 of other drivers which may get bitten by that :/
 I'm fairly sure that used to work though, at least sbus and UPA =20
 framebuffers are set up even if they're not the console.
 
 Does this help:
