You need some sort of video library that writes directly to the video memory
of the Geode, giving you an API for things like drawing bitmaps and
rectangles (the progress bar). As soon as the bootloader starts and
stabilizes the RAM, initialize the video controller in the Geode, clear the
screen, enable video output, and draw your bitmap. As the nk.bin file (or
whatever it is that your progress represents), is loaded, draw rectangles in
the right place to show progress.

You might look through the code from the Geode guys for such a graphics
library (we got the one we used from our video controller vendor)...
