I don't know any documentation about this. But a good reference are the schematics which can usually be found easily on the web for these old Thinkpads. Just google for the code name[2], this one should be nozomi-4. Don't know if this is exactly what you are looking for. But there are two headers shown, much like in the "example" *wink* ;) picture attached. There, J27 is for emulation of both flash chips and J14 is for directly flashing the second chip. I guess J14 can be used for flashing the first chip too, by using -SPI_CS0 from J27. But you will definitely want to attach VCC at J14 because that's where the board is protected by a diode.
