AFAIK dellflash (well, at least the Linux equivalent) is special because it doesn't perform any flashing, it simply loads a BIOS image into contiguous physical memory and waits for the BIOS to do the flashing on reboot. Due to that, you need a kernel module, and the flashing happens outside any OS. flashrom doesn't trust/use the BIOS to flash, and it doesn't need a kernel module because it does the flashing itself, from userspace.
