There isn't. Feel free to write a module to do it (see how the ioctl
handles it and follow the same logic). Its at best a hack. libata is
trying to add proper hotplug for ATA/SATA.

I wrote a module to do the register/unregister through a /proc file.
It currently only works on ide1; the constants in scan_hw and unreg_hw
should be made to depend on the value written to the /proc if other
interfaces are needed. Available at
