Hello,
As written in the use of Flashrom and on the page http://www.flashrom.org/Random_notes/MCP_SPI_support, I send you my verbose file.
I can help you, if you want, to test patches as long as I know I can recover if it doesn't work (I would prefer not to loose my laptop I bought 6 mounths ago...).
Feel free to contact me if I can help.
Good luck, Maze
