Visual Studio (6.0, 2003 & 2008) compatibility with Windows Vista 64-bit (x64)

Are there any compatibility issues with running Visual Studio 6.0 (including Visual SourceSafe 6.0 Client), Visual Studio 2003 & Visual Studio 2008 on Windows Vista 64-bit? Can I interactively debug the applications with the Vista Web Server? Can I still make/compile projects? Is it correct to assume that Visual Studio 6.0 & 2003 will execute under WoW64 (Windows-on-Windows 64-bit), while Visual Studio 2008 is native x64? I note the "Support Statement for Visual Basic 6.0 on Windows Vista and Windows Server 2008" (http://msdn.microsoft.com/en-us/vbrun/ms788708.aspx) states "VB6 development on 64-bit Windows is not and will not be supported." I found some usernet/newsgroup discussions of other folks trying similar endeavors - 64-bit OS, apps for Windows development PC? - Can't install VB6.0 on computer with Vista 64-bit OS
