Could you arm me with a small test program that writes to that bottom section? I gotta figure out what I'm doing wrong here.

See the attachment for a crappy demonstration how it should work. I'm running a bit more modifed kernel than the diff file I previously posted, but it should work still. Note, that when you are blitting stuff in the overlay mode, it's only the 1/4 bottom of the screen buffer which actually gets blitted into the screen.

When you run the attachment with the kernel mod, it should blit garbled random image into the screen every second for 15 seconds. If you want to test this with the player, you can do this:

overlay_display &
/empeg/bin/player

And if the player is not in stand-by mode you should see some random dots to flicker in the bottom part of the screen approximately every second (for 15 seconds, till the program exits).

Let me know if you still have problems and I can try to make a better example or to explain it more.
