Well flashrom has numerous per-chipset and per-motherboard drivers for
the write-enable, the quantity of those would remain the same for an
in-kernel driver. The benefit would be that the drivers would tell the
kernel (/proc/iomem /proc/ioports) what is going on. Consider also that
there are per-chipset drivers in Linux for EDAC that flash rom functions
could be merged into.
There is always the option of the generic 4G - 16MB window for
