Sorry, I was mistaken here. I have a D600 (Bios A16) and suspend/resume is working for me without nomodeset. Maybe I'm not remembering correctly, but I do believe it wasn't working at one point. Having said all of that, my machine still goes to sleep properly even with nomodeset added to the boot parameters.
Regarding the nomodeset: I was getting my model confused with a friends laptop, a D505. Suspend/resume was not working on that machine and adding nomodeset worked there.
