IIRC, the problem is that the version of DEVFS that we have now can't handle device arrival/removal events from an interrupt context. Julian had a version of DEVFS/SLICE at one point that could handle being called from an interrupt context, however. Bruce looked into the DEVFS/CAM thing a while back, and conculded it wouldn't work for now. If you want details, ask him. So, the bottom line is, if you're using CAM, you can't use DEVFS.
