i've tried using flashrom for reading the SPI Flash of my Thinkpad X60s. It seems like it is using the (yet) unsupported M25P16.RES. I've added the few lines required to get it working, and at least reading the Flash works. Haven't tried writing the Flash (yes, i know about the risk regarding EC and friends) ;-)

Hi Sven, [adding flashrom@flashrom.org to CC]
thanks for your patch.
Please note that a huge number of incompatible chips share the same RES ID. A quick glance at my datasheet collection (I stopped after 5 minutes) resulted in the following matches: AMIC A25L016, A25L16P Eon EN25P16 ESMT F25L016A Generalplus GPR25L161B Macronix MX25L1605*, MX25L1635* PMC Pm25LV016B Spansion S25FL016A ST M25P16 Winbond W25Q16*
Are you 100% sure you have a ST M25P16?
Regards, Carl-Daniel
Your mail follows unqoted so flashrom patchwork will pick it up.

i've disassembled my X60s yesterday, and indeed it is not a M25P16. Instead it is a MX25L160AM2C. So i think the best is to discard this patch. I'll send an updated one after i re-assembled my X60s (which may take a while, as i'm trying to fit a SXGA+ TFT in it)
Regards and sorry for the noise,
Sven.
