Was your gcc and binutils built with USE=vanilla? If not, it is
completely possible that your toolchain produced a broken image.
I've had this happen with some gcc versions.

CMOS/NVRAM? That may need to be enabled for image to work.

How did you set this exactly?

Get a docking station, port replicator or ultrabay superio module, so
that you get a serial port, and connect that to another computer.
coreboot should output debug information there when starting, and it
may be clear what the problem is.

Also, does it seem like the system boots? Is there some hard drive
access after you power on?

And, does caps lock work after you power on?

Finally, did you include a VGA BIOS into your coreboot.rom? This is
easiest done by configuring the filename in menuconfig. Note that
coreboot should not execute the VGA BIOS, the file should only be
added. You may need to change the defaults for this.
