That may be useful in some scenarios, exspecially for experiments and temporary mounts. Seems also to be used by some (most?) life-CDs for the disks found. > Just wanted to add this in.

I think the kernel does not do any partition detection except on boot. When you hotplug a disk, udev may be what actually does the partition detection on it, probably using a similar mechanism as partprobe or kpartx. I may be off here, but so far partprobe has worked well for me, due care stipulated (i.e. do not start to change mounted or mapped partitions and the like).
