Hello Erik,

thank you for your contribution. I had a look at the driver. But before
going into the details I would like to learn more about the display.

Does it support something else than displaying plain text? Does it use a
'standard' controller that supports custom characters? How is it
connected to the system (I/O, serial, USB)? Does that interface require
exact hardware timings? Does it have keys?

And what are your plans / ideas?

In the current state the driver does not differ much from the "text"
driver except it outputs to your kernel driver pipe instead to stdout.

Therefore I vote to not add a separate driver but perhaps modify the
"text" driver, although I am not to decide about this.
