I tested the newer kernel without the workaround, and I am no longer experiencing kernel panics on my X60s on the second suspend. However, my screen only powers on when I have the e1000 module whitelisted. The machine resumes properly otherwise and I can type commands blind or suspend again by shutting the lid. When I do have it whitelisted, the screen comes on fine. (I tested this six or seven times with each configuration.) I don't understand how these two are related and was quite skeptical that they were, but I guess they are.
