How exactly is that different to an undocumented or—forbid it—an unflashable BIOS? Don't even get me started on EFI...
Aside from coreboot, I don't really see anybody drawing the ideological-line-in-the-sand there when it comes to running their PC.
Well perhaps a better example might be System Management Mode on Intel CPUs, which easily allows for undetectable backdoors with constant access to the same physical memory as anything else running on the CPU.
