There is a fbcon module as is referenced in the pygame script you listed
from Adafruit. I would suspect that none of the drivers listed in the
script ('fbcon', 'directfb', 'svgalib') would be loadable on your system.
>From what I have gathered, fbcon is enabled by enabling the Framebuffer
console feature in the kernel as in the .config. I'm not 100% sure how to
do this with the BB kernel.
When my BBBlue was still alive (R.I.P.), I did connect a ili9341 display to
it and had to run the following to get a QT app to run on the screen:
# <qt_program> -platform linuxfb:fb=/dev/fb0
This is the example I followed which was posted by Jason.

Perhaps something similar would work for the BB Black and pygame.
Cheers,
Jon
