Hi Joe,

thanks for your report.

Sure. Please download latest flashrom from our svn tree and compile it.
That one should have full SPI support for your chipset, and thus find
your flash chip easily.
Write is not yet active on your chipset because we wanted to gather
enough user reports, but now that we got lots of success reports, I
think I'm going to enable write as well in the next few days.
