I have not read the page in full detail, just curious: was it necessary to unsolder the chip, was it not possible to program it using flashrom from Linux command line instead?
It may be possible. the main problem is the lenovo bios update. It's still unknown how it's updating the rom. But the lenovo protects the bios region from writing. AFAIK there is a *scratch* region writeable possible for bios updates.

This guy succeeded in (software) flashing a modified Embedded Controller firmware bypassing the crc checksum. I wonder if a similar method could be employed to flash the BIOS portion as well
