Thanks. I already had a basic driver complete, but I was unaware that
I needed to implement ANSI escape sequences. That tip was exactly
what I needed. I've added the relevant sequences and it's now working
nicely with Ncurses.

Care to share? Seriously, it would be nice to have an ncurses-capable
screen.

Well, I haven't made the code very portable at this point, since I was
only intending it for this application, but I'll have to talk to my
employer to make sure it's okay for me to release it.

Now that I've got the LCD up and running, I'd like to print a welcome
message as early in the boot process as possible. Can anyone provide
some advice as to how I'd go about doing that?

Depends on your boot sequence. I'm pretty sure you could patch redboot
to stuff a logo out. Otherwise add a routine to the kernel to do that
on boot.

I'm working on patching U-Boot with a driver now, though I was
sidetracked for a while as I somehow screwed my toolchain up.
