Now I found time to finally play with it a bit. It's actually great to see the display spitting out images at that pace. It shows the capabilities of the display quite well. Here on a K3, it spends most of its CPU time in kernel space, probably chewing within the einkfb driver.
Makes me really want to port ScummVM... Also it would be a good fit for a prdoom clone based on this. Yes I know that there has been a grayscale based port.
The hard part about audio would be syncing video and audio. OTOH, audio output might provide a cheap approach towards a timing source one could re-use for the video output, too.
Did you test LZO compression? Might be easier on the CPU, plus your program could implement it itself and decompress directly to the framebuffer, saving a copy. Compression ratio will probably be worse, though.
