AFAIK, XP ships with at least 2.7 MDAC installed, which can be seen
in registry (at XP)

HKEY_LOCAL_MACHINE \ Software \ Microsoft \ DataAccess [Version]

You can also check for installed ADO from code:

// Untested

double GetADOVersion()
{
   CoInitialize( NULL );
   float Result = 0.0;
   try
   {
      Variant Ado;
      Ado = CreateOleObject( "ADODB.Connection" );
      Result = Ado.OlePropertyGet ( "Version" );
      Ado.Clear();
   }
   __finally
   {
      CoUninitialize();
   }
   return ( Result );
}
