Looking over phk's comments on retiring md5crypt 
(http://phk.freebsd.dk/sagas/md5crypt_eol.html), I note that he says:

 New research has shown that it can be run at a rate close to 1 million
 checks per second on COTS GPU hardware, which means that it is as prone
 to brute-force attacks as the DES based UNIX crypt was back in 1995: 
 Any 8 character password can be found in a couple of days.

Given CPU speed, DES is presumably weaker today than it was in 1995.
Is there a reason for assuming that md5crypt is worse?

That sounds like it would be ideal.
