No. Such a system is not completely free. I'm not that knowledgeable on the
subject myself. I was informed of the issue by the/a lead coreboot developer
a few years back. At the time I was told it is a bigger issue than the BIOS.
My understanding is that if we are really going to release a completely free
system its going to have to be based on a non-x86 architecture.
This is not something we are currently working on so I can't really dig into
it further. It's more of a project for the future. Right now we are just
working on building relationships, distribution channels, and financial
capital that'll make such projects possible. The smaller projects like a
freedom friendly USB N adapter is our largest current endeavor (it is a large
project which requires significant investment).
