Yes. Windows effectively does by virtue of the fact that it ships he
firmware *with* the driver and even if it's in a separate file (which
it often isn't), the signed manifest covers it all together.
Look at it this way: If you don't have an IOMMU, then signing modules
is *utterly* pointless unless you also sign firmware. A rogue device
can do *anything*.
We really do want firmware signing for the *OS*, not just for
regulatory issues and other vendor-interest stuff which was Luis's
original focus.
