Just checked the datasheets: The NVRAMs of the UltraBooks I know of are the 
DS1643 and the DS1553. Both should be similar enough to be read/write by any 
reader that supports the DS1643 or the DS1553. Of course I'd offer creating an 
modified Arduino doing the task, to test it and to supply it to anyone who is 
willing to dump his NVRAM!!!
