This is the second mainboard that I try showing a message about finishing support for the W836xx Super I/O, the first was http://www.flashrom.org/pipermail/flashrom/2014-June/012651.html let me know if I can do more to help.
Here is the output of flashrom -Vw for a successful write:

Thanks. ======================================================================== WARNING! You may be running flashrom on an unsupported laptop. We could not detect this for sure because your vendor has not setup the SMBIOS tables correctly. You can enforce execution by adding '-p internal:laptop=this_is_not_a_laptop' to the command line, but please read the following warning if you are not sure.
Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and http://www.flashrom.org/Laptops for details.
If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== Proceeding anyway because user forced us to. Found chipset "AMD CS5530(A)" with PCI ID 1078:0100. Enabling flash write... OK. The following protocols are supported: Parallel.
