Ah, see that's what I was hoping for. So, there is indeed no reason not
to use DSA-1024 with SHA-512. Just as there is no reason not to use
RSA-4096 with SHA-512. But the OP was talking about RSA-2048 (with any
hash), and there is a reason not to use that. I was assuming that the
mention of DSA-1024 with SHA-512 was meant as an analogue to
RSA-2048. Apparently it wasn't.
