This should not be an issue. If you need driver for it you can just download them from the Wacom website.
The serial number woudl only really be used if you ever rang up a technical support team, but if this is an Intous 3 it is either out of warrenty or nearing being out of warrenty
And if you were using this with a mac you could use it as a "mouse" with the pen without installing any drives but quite a lot of the funtionality on this will not work - I.e. the rock buttons wont work, neither will the modiferyer buttons on the tablet itself.
