Especially, not specifically. I was just saying my options are more limited, and the options for someone unwilling to recompile their own software is very severely limited. But even if I'm running, say, software-only Salsa20 with all compiler optimizations off, if my CPU is still owned, my keys are still at risk of silent compromise. The only real defense is to ascertain the processing limitations of IME and then choose your crypto primitives/implementation for both processing and memory hardness that exceeds the ability of the IME's lower transistor count and/or clock speed to keep up with.
