Is it an X60s? Apparently so, but flashrom does not seem to support it.
sudo ./flashrom -p internal -V
Internal programmer initialization failed (see [1], no modifications made to flashrom).
I changed the entries accordingly for either Macronix or SST. Lenovo site says X60s, DMI (according to flashrom) says it's a T43p.
(testing now with external programmer)
