Not really.. Just write an app that you know will call LdrLoadDll (either some framework function will call it or you can call it yourself), run that app, ATTACH to that app, and set the bpx.

You, of course, know that ntdll.dll is AUTOMATICALLY being proected into the address context of the process before symbol loader pops up, before main, before everything. And it is not reasonable at all to create any Native API application. So I myself will try to play with Lunar_dast suggestion. Unfotirnately it seems to be the only real way...
