No, you can add attributes to it, I just don't think the pointer is
accessable for a tty driver to be able to find the thing. Need to go
look at the code again to verify this or not.

No, that's the proper way to go.

It's scheduled for whenever someone gets around to doing it :)

As there is no 2.7 tree, nor is there going to be, why not do it right
now? I'd gladly take patches that do this, and I don't think they would
be all that big at all.

No, I will not allow that to go into the kernel tree, sorry. Just
export the tty class pointer in the proper structure, and you should be
fine.
