Dear Peter,

This happens because CONFIG_NONPROMISC_DEVMEM (pre 2008-07), CONFIG_STRICT_DEVMEM or CONFIG_X86_PAT are set in your kernel.
Although flashrom can do nothing about any of these, I will add this information to the error message, so I'm not closing the ticket just yet.
There is an entry in the FAQ for this issue [1].
Thanks,
Paul
