well PCB is costing nearly 6.5k right now ... and IC arent available ... and i just modded a september and november 2010 0225 drive and it turned out to be a MXIC .. wrote LT1.9 to it no probs .. on the other hand ... encountered a xbox august 2010 but the drive was a winbond ... so i guess its just a matter of luck ... get yours checked .. might be a MXIC ...
