Attached is dmesg and iomem from the working kernel
(I just booted a Fedora 14 live key on the same system
and flashrom works fine).
Nothing obvious from the iomem diff:
(02:00.0 is the ethernet controller BTW)
$ diff broken.iomem working.iomem

dmesg shows some differences in the memory maps
but I'll need to do further investigation to
be able to interpret these differences:
