No, NM shouldn't be touching /sys at all. That's HAL's job. If there's a device out there that's an 802.11 device, NM will attempt to control it. I don't really see why that's wrong. What's more wrong is representing the same underlying device with separate _wireless_ devices. Normally (atheros, airo) drivers that have "special" interfaces set other bits on them so they get ignored. This sucks though, the raw 802.11 stuff should go through other channels, not have to create a completely separate device. I assume what you'd like to do is have NM ignore the fact that you just turned on some sort of "raw" mode on the device. Unfortunately, WEXT doesn't give us the flexibility to OR the modes. Ideally "raw"/"monitor" would just be attributes of the device that wouldn't really affect it's normal operation. WRT the disconnection, please run 'iwevent' during your packet injection runs and see if the driver sends you an SIOCGIWAP event filled with zeros, meaning that the driver disconnected you. Also please run a few 'iwlist ethX scan' commands about 30 seconds or more apart during that run, and see what the 'iwevent' says. My suspicion is that doing scans during the injection while associated makes the card hiccup, causing NM to notice the disconnection event and kill the connection (rightly so).
