Overlay patch for 2.0?

I tried to modify empeg_display.c based on Kim and Kit's overlay patch and was unsuccessful. I think it's blocking off the display but I can't seem to write to it, so I think I goofed up while trying to graft in the overlay functionality. Either of you guys have the overlay stuff figured out for the 2.0 beta kernel and care to share your empeg_display.c? I have no idea what I'm doing wrong but it's just not working.
