There was a TODO comment to replace static SPD EEPROM data with dynamically generated one to support this. Now that we have a function for that, it's easy to do. Although this would allow larger RAM sizes, the peculiar memory map of the machine may need some special handling to map it as low and high memory. Because I don't know what the correct place would be for highmem, I've left memory size fixed at 256M for now and TODO is moved there instead.
