I nailed down the issue with the remoting tests. I have a patch to fix it but
it looks like a big hack than a proper fix. The patch to
mono_runtime_invoke_array does the following:

+pao = mono_array_get (params, MonoObject*, i);
+pa [i] = pao;
+if (pao != NULL && !mono_class_is_assignable_from (par_class,
pao->vtable->klass)) {
+       if (pao->vtable->klass != mono_defaults.transparent_proxy_class ||
!mono_class_is_assignable_from (par_class,
+               mono_raise_exception (mono_get_exception_argument ("",
"Incompatible type passed"));
+       }

In some cases the object type is TransparentProxy instead of the object itself.
I'm still not sure why this happens and the way I'm handling it doesn't seen
right. I haven't been able to isolate the issue outside of running
System.Runtime.Remoting test suite.
