Line 432: 	mdelay(120);

So this is a panel-dependent value? Isn't there anything in the datasheet about how long the panel needs for this initialization? I would feel much better with that then "it seems to work with more than 120ms for some reason". (If we can't find a source, we should probably have a little more margin... maybe 150ms. But an official number would be much better.)
