BTW, while fiddling around trying to find the
corrupted-display-after-reboot problem on Seaboard, I turned off/on
random display-related things. IIRC, when the panel VDD was off, but the
backlight was on, the display was all-white. Now, there are probably a
ton of other reasons that might happen, but that one would be simple to
verify with a few "gpio set" or "gpio clear" commands on your system...
