hello again
this looks like it needs way more work than i thought in the beginning. the flash chip is probably behind the super i/o chip (fintek F71882) which flashrom does not yet support. there has been a patch in the works for a long time, but i think there was not much demand/testers to finish it.
could you please apply the following patch to r1455 of flashrom, recompile, run flashrom -V and send us the log? http://patchwork.coreboot.org/patch/3440/
this will *not* enable you to use flashrom as a programmer, but it might induce further development. i think it is safe to test (no flash access is done). i will inform the author of the patch that a new victim^Wtester arrived ;)
