dlang: "they can also modify anything else in your kernel, so why would they
go to the trouble of targeting a specific piece of hardware when they can do it all from the
common x86 compatible cpu"

To make malware resistant to software reinstall on hardware with some reprogrammable memory.
If firmware malware works badly, it makes normal administrator to trash the hardware. If
firmware malware works fine, it sits there for long and being resistant to many current and
common schemes to prevent and detect malware. Not many of us do reflash hardware, which have
worked fine. At least it goes quite far away from current threat models.

I think the scope of target doesn't have to be limited to specific hardware, but to cracking
software, which can be run once on a compromised system. The software could know more
hardware.
