There is currently a driver for the LCD, but only with a framebuffer (no
window system).  UART has kernel output on it (if switched on); it is
trivial to turn it into a driver.  I2C currently has no driver, but it
seems that that shouldn't be very hard.  Audio currently has no driver,
and that may be quite a task, but it must be done for the Ben anyway.

There's currently only support to boot from usb, but I want to add a
nand driver as well.

All in all, there's some work to do before it does what you want.
Depending on how much time you have, this may or may not be a problem.
