Is there a link to an image for the board (and flashing directions) on your website?
No, there isn't. Which SST chip do you have? 49LF080A or 49LF004B? I can send you an image off list.
Flashing instructions are to use flashrom -w imagefile.
Flashrom is available as a package in OpenWRT, but from memory I think it looks for /dev/cpu/0/msr and OpenWRT has /dev/msr0 instead. Create a symlink to get it to work.
Running flashrom without any arguments will tell you if the chip is detected correctly. You can also verify an image with flashrom -v imagefile.

Let's see... peeling off the "0.17" sticker reveals... 080A...

Ok, got the image, downloaded and installed flashrom-0.9.3 and dmidecode to the target (a Traverse Technologies Geos), and I'm getting:

I'm going to guess that the message "No coreboot table found." should be worrying.
