Followed the coreboot wiki entry perfectly, and had no issues reading the flash chip.

The 4MB Bios chip in my x1 differs from the Wiki Entry:

Found Micron/Numonyx/ST flash chip "N25Q032..3E" (4096 kB, SPI) on linux_spi.

Not sure if that impacts anything, however booting I am faced with a Black Screen.  Fan is not running at all, and appears nothing is happening.

I found this link as well:  http://coreboot.coreboot.narkive.com/zUOsG1zN/lenovo-x1-carbon-3460-screen-stays-black

Flashed the rom at the end of the suggested mailing list comment, and still black screen. 

I have included the vbios in my build, so I'm not sure what's wrong.
