Worked fine on my LC-4OC3/POS-SM (eng 0). A lot faster than "hw-module
slot 0 reload" and "reload slot 0". Btw, is "hw-module slot 0 reload
debug" (with gdb) also a new feature?

A note about my LC-4OC3/POS-SM card is that all interfaces are in
shutdown. Not in use for the moment. The IOS is 12.0(25)S1.
