Thanks for the compliment!

As for fbcon: I think you're confusing things. fbcon is not the same as fbdev.

I've hooked into the terminal emulator because it allows me to hide exactly the thing I want to hide (text), it allows me to show what I want when I want (splash or text), and it spares me from defining a third competing user of the device.

I understand that you want old code to die, and as it is now, catering for the old code will cater for everyone, including the new style drivers (via their legacy interface).

The current solution will "just work" on your systems as it is. I'm not ignoring them. If you've ever used a kernel console on your DRM ARM device, then the current splash will work exactly as good.
