hotplug.c: add a second switch to parse_args()

Browse Source 
Add another level of option parsing to allow usage
of string values.
Currently all values are converted to long
(or have to be checked before the switch),
which results in errors upon adding a string as a value.

This is going to be used in the next patch in the series.
