I did some projects a few years back with the Olimex boards with a Nokia display. The ones where the display was double sided taped to the PC board.
They worked fine until I took them outside with a lower temperature. They wouldn't wake up.
The fix that I finally found involved increasing the contrast value in 4 steps with a delay between each step. A one step contrast increase would cause the power to latch up. Four steps allowed the display current draw to adjust and not exceed the latch point. I no longer have access to the code for this.
