The trouble with this is simply, that some modern BIOS store more information than others, especially in areas not accessible by /dev/nvram. SuperMicro has a few boards storing 256 byte(?) instead of he allowed 114 bytes. Also, at least in some of their A-series boards they seem to store the date of the last flash (or something related), thus even hacking the kernel module to read more data would not help much, since the md5 hash of each image will differ anyway. Thus one would have to reverse engineer where what is stored... quite a hassle.
