I am a big FreeBSD fan, and also run NetBSD on an older machine. Haven't used much Linux lately but installed Ubuntu to get a lspci for flashrom use. Ubuntu is fine, but does not have superiotool available as best I see. Looking back to FreeBSD I found superiotool just where I expected, as a port to be compiled under sysutils. Works fine, but still never finds my hidden bios I will call "SPI1" for lack of a better name.
Anyway, I keep looking for more tools, and have an extra disk drive for another OS if anyone has any good suggestions?
Right now I'm in Ubuntu, listening to the coreboot & flashrom freenode IRC channels. Quite a lot goes on there if you catch it right. Some real sharp guys.
