Yeah, I'll annoy people again with patches until they're merged ;-)
Iirc Andrew picked them due to lack of an fbcon maintainer, and
everyone else likes to pass the bucket. Having looked through the code
a bit, imo understandable ...

btw, I've started to look into how we could fix the locking madness
around fbcon for good instead of with duct-tape [1]. I'll try to
discuss this with a few fbdev guys at fosdem (some at least should be
there). Certainly a long-term thing, but comments from whomever gets
volunteered to shepherd fbcon would be great.

Cheers, Daniel
