The I/O range of the LCDs is only 0x1c8. Why do you set it 0x1000?

Actually, a more correct value would be 0x10000, if you read table 145. Yes, the device may onlny have documented registers from 0x84 to 0x1c8, but that isn't to say that we should say that the device resources start at 0x810084 and have a size of 0x144, when the bus level decodes a 64K chunk of memory.
