I think he meant something that would include the part he remembered, 
and  'guess' the remainder.

Along the same lines have you considered just making a list of the 
possibilities, then scanning it by eye to see if something jogged your 
memory. If you have a way to generate the list quickly, it might be 
worthwhile.

That depends on the type of passwords you use, though.
If they're like: fK^3klP9jYdd7+Hg0awV, you can probably just forget it.

I use stupid phrases for my passwords, so something like that would work 
for me, if I could only remember the first part.

Examples:
29ClownsR282Many!
