Any way to display custom graphics on the Kobo Wifi?

[KevinShort]

I've been trying lately to display custom images on my Kobo Wifi. I've had no luck
finding any documentation for the Wifi's imx357 and e-ink on freescale's website,
and pygame fails to recognize the framebuffer. So I tried converting an image to the
rgb565 format with ffmpeg:

ffmpeg -vcodec png -i image.png -vcodec rawvideo -f rawvideo -pix_fmt rgb565 image.raw

and displaying it with the program "pickel" found on the Wifi, but the image it displays
is distorted, as seen here (original image is shown in top-left corner):


Anyone have any suggestions? I can't stand having my Wifi hacked and yet not being
able to draw to the screen! Plus I need something to do until I can get my hands on a
Glo or a Paperwhite.

I was wandering through the the files on my Wifi when I, on chance,
found the file "/sys/class/graphics/fb0/rotate". I saw that I contained
a single "0", so I tried

echo 1 > /sys/class/graphics/fb0/rotate

to see if anything happened. Nothing did. But, for some reason,
pygame could suddenly see and draw to the framebuffer!

I still have to rely on 'pickel' to update the screen:

dd if=/dev/fb0 of=screen && cat screen | /usr/local/Kobo/pickel showpic

Pygame on my Wifi doesn't support png alpha, but colorkey alpha works.
Text rendering works as well, but both the text color and text background
color must be specified, otherwise it will come out as a solid rectangle.
