Yes.... Installing service pack 2 was a little awkward as I had to download it and burn it to a CD and point the VM at my physical drive X:\WindowsServer2003.WindowsXP-KB914961-SP2-x64-ENU.exe
but after that the Integration Services installed without issue and the network device passed from the host and everything was right with the world. No need to install any legacy NIC or anything. It just worked.
Hope it works for you as well.
NOTE: And there is no SP3 for the 64bit Version of XP Pro that I could find anywhere.
