Lenovo x201i also uses a Macronix MX25L6445E chip and I'd like to give it a try using a Bus Pirate (ver. 3.6).
Which BIOS<->Bus Pirate pin assignments + serial mode are you using? Is the 'additional power supply' provided by the '3V3' pin on the Bus Pirate or an external power supply? Are there any special instructions on keeping the laptop powered or should the laptop be fully 'off'?
