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

root at OpenWrt:/# flashrom -w /tmp/coreboot.rom
flashrom v0.9.3-r1205 on Linux 2.6.37 (i586), built with libpci 3.1.7, GCC 4.5.2, little endian
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Bad table checksum: e18c.
No coreboot table found.
Found chipset "AMD CS5536", enabling flash write... OK.
WARNING: unexpected second chipset match: "AMD CS5536"
ignoring, please report lspci and board URL to flashrom at flashrom.org
with 2CHIPSET: your board name in the subject line.
This chipset supports the following protocols: Non-SPI.
Found chip "SST SST49LF080A" (1024 KB, LPC) at physical address 0xfff00000.
Note: If the following flash access fails, try -m<vendor>:<mainboard>.

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