I can't agree with this.
SHA-{256,384.512} can be used with RSA keys!
RSA keys can be much larger than 1024 bits, so why stick with only 160 bit hash?

well.. I could agree that SHA-256 is enough and SHA-{384.512} is overkill.
but SHA-{384.512} my be useful for ones with 64bit CPUs - SHA-{384.512} is
significally faster than SHA-256 there, almost as fast as SHA1.

besides SHA-{256,384.512} can also be used with Elgamal signing keys,
but these keys are unpopular, so no big deal.
