I've written a rom file with 'flashrom -w romfile.rom' and verified afterwards with 'flashrom -v romfile.rom'. The result was "VERIFIED"! On the congatec board I just tried to erase and read again, have a look at the attached output... I don't know if it's correct...
To the other systems i currently don't have access, i hope i'll be able to try the erase and read procedure in the future.. The write and verify worked out of the box! If you need, i can provide logfiles from the write and verify of each board!

Hi... I just tested flashrom on a bunch of mainboards:
SST49LF008A congatec conga-x852 SBC (http://www.congatec.com/single_news+M5e8f9751886.html). Read, write and erase works out of the box. I also verified with the original congatec tool. It reports success! SST49LF008A IEI PICOe-9452 (http://www.iei.com.tw/en/product_IPC.asp?model=PICOe-9452) Everything
ok... SST39SF040 LEX Systems CV700A (http://www.lex.com.tw/product/CV700A_s.htm) Everything works fine... SST49LF004A/B Portwell PEB-4700VLA (http://www.portwell.com/products/detail.asp?CUSTCHAR1=PEB-4700VLA) Everything works fine..
Nice, thanks! Did you run the write with the -v (verify) option a la 'flashrom -wv foo.rom' and did it report "VERIFIED"?
Did a 'flashrom -E', 'flashrom -r empty.rom', 'hexdump -C empty.rom' report only 0xff lines?
If yes, all of the boards do work nicely out of the box, indeed. We can then update the flashrom code and the wiki.
Btw, the LEX Systems CV700A has a VIA VN700 / VT8237R chipset, so it could be supported by coreboot quite easily, if you're interested.
