I would have swapped the if/else branches, i.e. if (ret == 0) /* hard
error */ else /* possibly due to another failure */, but that's just my
weird taste probably :)

I can not imagine how this could possibly break anything in vanilla
flashrom. I have also tested it with the dummy programmer:

$ ./flashrom -p dummy:emulate=M25P10.RES,fail
flashrom v0.9.6.1-r1707 on Linux 3.8.0-6-generic (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Unhandled programmer parameters: fail
Aborting.
Error: Programmer initialization failed.

$ ./flashrom -p dummy:emulate=initfail,image=persistent.img
flashrom v0.9.6.1-r1707 on Linux 3.8.0-6-generic (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Invalid chip specified for emulation: initfail
Unhandled programmer parameters (possibly due to another failure): 
image=persistent.img
Error: Programmer initialization failed.

Hence...
