Well, for that purpose it's much better to simply use flashrom.

Probably, but flashrom takes slighly more time due to various calibration routines (I could not find a way to disable those, but I didn't try very hard), and is less integrable that just reading like this. I don't need much portability between mainboards anyways.

In the general case however, you are right, the flashrom method seems much more robust.
