AFAIK swappable hardware needs to be supported by the hardware as well.
Currently hard disks and power supplies can be hot-swapped, I never heard
of the possibility to hot-swap directly on the data bus (memory, CPU, slot
cards).

As for SCSI disks and Power supplies, Linux supports hot swap. Check out
Dell servers for example.
