Nope, Linux doesn't magically replace all the firmwares. You typical PC
has a multitude of processors, and you only (mostly) control what runs
on one class, the general-purpose CPU. You don't control what runs on
the NIC, storage controllers (e.g. RAID), storage devices (disk drives,
DVD drives, etc.), video cards, etc. Linux still has to deal with SMM
and ACPI that is not Open Source.
