RegisterServer

I have a COM object I'm trying to port to x86 CE 4.20 from ARMV4
PPC2003. My PPC2003 SDK had ATL 8.0, but my CE 4.20 SDK only has ATL
3.0.

I finally got everything to compile, but when I go to register the COM
object, I get the error:
0x80070716 "The specified resource name cannot be found in the image
file."
from CComModule::RegisterServer() in the DllRegisterServer() function
of the Dll.

In ATL 8.0, I had

class CMyModule : public CAtlDllModuleT< CMyModule >
{
public :
    DECLARE_LIBID(LIBID_MyLib)
#ifndef _CE_DCOM
    DECLARE_REGISTRY_APPID_RESOURCEID(IDR_MYAPI,
"{AA78BE74-4F51-49C2-9B5C-26B0AEABB40C}")
#endif
};

CMyModule _AtlModule;

extern "C" BOOL WINAPI DllMain(HANDLE hInstance,
                               DWORD dwReason,
                               LPVOID lpReserved)
{
    hInstance;
    return _AtlModule.DllMain(dwReason, lpReserved);
}

STDAPI DllRegisterServer(void)
{
    // registers object, typelib and all interfaces in typelib
    HRESULT hr = _AtlModule.DllRegisterServer();
    return hr;
}

and all that worked great. But, for ATL 3.0, I've got to do something
like this:

CComModule _Module;

BEGIN_OBJECT_MAP(ObjectMap)
OBJECT_ENTRY(CLSID_MyInterface, CMyInterface)
END_OBJECT_MAP()

extern "C"
BOOL WINAPI DllMain(HANDLE hInstance, DWORD dwReason, LPVOID
/*lpReserved*/)
{
    if (dwReason == DLL_PROCESS_ATTACH)
    {
        _Module.Init(ObjectMap, (HINSTANCE)hInstance);
    }
    else if (dwReason == DLL_PROCESS_DETACH)
        _Module.Term();
    return TRUE; // ok
}
STDAPI DllRegisterServer(void)
{
    // registers object, typelib and all interfaces in typelib
    return _Module.RegisterServer(TRUE);
}

Can anybody tell from this where I'm going wrong?

Thanks,
