OK, here is a patch which should be used with latest flashrom to flash
the new BIOS image. This patch will shou up at
http://patchwork.coreboot.org/ in the next few seconds.
On top of it, you need to apply
http://patchwork.coreboot.org/patch/1171/raw/ as well.

Please apply the patches, recompile, then run
./flashrom -V -c SST39VF040 -w 480401.bin
