White Screen Of Death, LCD controller

[polz]

Some people have mentioned a white screen of death occuring on their 
freerunners. The problem doesn't seem to be limited to the new hardware, 
though - I've had it happen a few weeks ago on a Neo1973. After a resume, the 
screen was white but the touchscreen was working and I was able to ssh into 
the phone. After the phone suspended and resumed once more, the screen seemed 
to be back to normal.
Since the problem (sometimes, randomly) also occurs on the Neo1973, Glammo 
might not be the culprit - the problem might lie with the LCD controller.

On a related note - if I change the resolution of the LCD to 320x240, the 
colours seem a bit odd. What should be done to fix that ?
