have hot-pluggable disks under the control of GEOM?

It is a function of the disk controller and driver. AFAIK, the ata
driver supports hot-plug as long as the SATA controller does. I believe
most Promise and Intel ICH SATA controllers do, not sure about Sil or
nVidia MCP.

If you where using SATA disks on a SAS controller then I think you would also need a back plane with an environmental services controller on it to support hot plug.
