No. Unfortunately, CAM is not newbus-ified, and thus will not send
devctl events. ATA disks will in 6.X and higher, though.

Yep. You should be able to work backwards through the CAM subsystem to
obtain this information. Take a look at the output of ``camcontrol
devlist -v''. The information is there, and you can use libcam to get
it.
