Doesn't pgp 5.0i for Unix support this? I remember having generated a

sec   1024D/624B3B3E 1999-10-26 Johan Wevers <johanw at>
uid                             Johan Wevers <johanw at>
ssb   3072g/1B240FEE 1999-10-26

where gpg complained about insecure key type, once with this version (that,
BTW, has a RNG bug that compromises security), but I already had it revoked
for another reason before this GnuPG bug was discovered (the key was already
possibly compromised, even without faulty signatures).
