Please double check IDSOPT_IDS_ENABLED.
I have first-hand experience with Rudolf's suggestion to use that #define, I have an F2A85-M as well. With IDSOPT_IDS_ENABLED, the serial output is significantly longer. I suspect the build system does not catch the change since it's not in menuconfig.
Perhaps try 'make clean' followed by all the normal build steps?
I tried several times but I still get the same result. I tried to start with clean git, and I've already used "make clean" to no avail. If in doubt, do not hesitate to create a rom for me that I test.
So the output now that I can get without this: coreboot-4.0-5454-g400c05c-dirty vendredi 7 février 2014, 09:25:15 (UTC+0100) starting... POST: 0x34 BSP Family_Model: 00610f31 cpu_init_detectedx = 00000000 POST: 0x37 agesawrapper_amdinitreset
