Nobody found my deliberate mistake ;).
Here is some code that will actually work:

   lua_newtable(L);
   lua_pushstring(L, "package");
   lua_pushvalue(L, -2);
   lua_settable(L, LUA_GLOBALSINDEX); /* set the global "package" to be
                                         the new table */
   lua_newtable(L);
   lua_pushstring(L, "preload");
   lua_pushvalue(L, -2); /* copy new table */
   lua_settable(L, -4); /* set package.preload to the new table */
   lua_remove(L, -2); /* remove "package" table */

   /* package.preload["lsocket"] = luaopen_lsocket */
   lua_pushstring(L, "lsocket");
   lua_pushcfunction(L, luaopen_lsocket);
   lua_settable(L, -3);

   /* package.preload["lmime"] = luaopen_lmime */
   lua_pushstring(L, "lmime");
   lua_pushcfunction(L, luaopen_lmime);
   lua_settable(L, -3);

sorry for the inconvenience :).
