When using the values in the tarball, or in your LCD setup (crt0_rom.S),
change the LYMAX value that I gave you from 239 to 240...  For some
reason, I had read the DragonBall manual as requiring LYMAX to be Max
LCD scan lines - 1.  This looks like another errate in the DragonBall
manual is needed by Motorola!
