Change subject: Add Lenovo Z61m laptop ......................................................................
Add Lenovo Z61m laptop
This platform shares most hardware components with first-gen Core Lenovo laptops such as T60/X60, with much smaller EEPROM size as one of notable differences. Several things like IrDA and LPT are not tested on this port yet.
