Don, installing Vista does not invalidate the XP product key. The Vista
license terms prohibit having a Vista upgrade version and the qualifying OS
installed at the same time but AFAIK the XP product key is not tracked on
the activation servers. MS doesn't know that that XP product key was used
as a basis for an upgrade. Heck there is a workaround to install and
upgrade version of Vista without XP being installed so it has no knowledge
of the qualifying OS product key.
The reason the OP needed to phone in activation for the XP install was
either because it is OEM version that's not BIOS locked, or it's a retail
version and it's less than 120 days since the last activation.
