Hello, err, Mr flashrom :^)
I suppose all the info you need is in the file.
There might be one more thing: if I try running flashrom from a Xen dom0, it fails, sometimes with a segfault, usually by logging me out. I'm still a Xen newbie, so I don't know whether or not this means anything - I just hope it helps.
