I've mailed Theo de Raadt asking if OpenSSH has an undocumented
mechanism for specifying minimum permitted key size that I don't know
about. If there is one, I'll certainly post a follow-up.

the new CVS versions of OpenSSH (the current portable CVS version doesn't
have the changes quite yet) allow you to specify a minimum key lentgh as a
#define at compile time. see ssh.h:

  #define SSH_RSA_MINIMUM_MODULUS_SIZE  768
