The required feature is ACPI support.  This will enable a number of
things including hot docking and hot swap support.  There is a project
underway in Japan (http://www.jp.FreeBSD.org/acpi/).  The last post I
saw mentioning when it would be integrated mentioned that it would be
added to -current after -current becomes 5.0 with some possiability of a
backport to 4.x-STABLE.
