You can then probably write a script/program to generate the possible 
passphrases (you probably know not only fragments, but perhaps also the 
general form of the parts you don't remember - where they numeric, 
alphanumeric, punctuation, how long were the parts etc.). So you should be 
able to narrow it down to a few thousand possible passphrases - then, 
depending on your coding skills, you can use a script that calls gpg (with 
--passphrase-fd; very slow) or a program that reads the secret keyring file 
and brute-forces it directly.

RFC2440 describes the binary format of the file you get when you do 
--export-secret-key (Hmm. On second thought - does it really? It only deals 
with public keys...)
