    For NT versions of windows, there's always been a "GetConsoleDisplayMode" function in Kernel32, but has only been documented for XP and Vista. But it works in 2K as well.
    Code:
    /*-----------------------------------------------------------------------------
    NT_GetConsoleDisplayMode - Get the display mode of the current console.
    
    Parameters:
        pdwMode - [out] A non-zero value indicates full screen
    
    Returns Values: 
        TRUE if successful, otherwise FALSE is returned. Call GetLastError() for 
        extended information.
    
    Remarks:
        This only works on NT based versions of Windows.
    -----------------------------------------------------------------------------*/
    BOOL NT_GetConsoleDisplayMode(DWORD *pdwMode)
    {
        typedef BOOL (WINAPI *GCDMProc_t) (LPDWORD);
        GCDMProc_t GetConsoleDisplayMode;
        HMODULE hKernel32;
        BOOL bFreeLib = FALSE, ret;
        const char KERNEL32_NAME[] = "kernel32.dll";
    
        hKernel32 = GetModuleHandleA(KERNEL32_NAME);
        if (hKernel32 == NULL)
        {
            hKernel32 = LoadLibraryA(KERNEL32_NAME);
            if (hKernel32 == NULL)
                return FALSE;
    
            bFreeLib = true;
        }//if
    
        GetConsoleDisplayMode = 
            (GCDMProc_t)GetProcAddress(hKernel32, "GetConsoleDisplayMode");
    
        if (GetConsoleDisplayMode == NULL)
        {
            SetLastError(ERROR_CALL_NOT_IMPLEMENTED);
            ret = FALSE;
        }//if
        else
        {
            ret = GetConsoleDisplayMode(pdwMode);
        }//else
            
        if (bFreeLib)
            FreeLibrary(hKernel32);
    
        return ret;
    }//NT_GetConsoleDisplayMode
