Why not simply keep track of the changes of the URL? Save the old URL to 
a table and search this before giving a 404. Then send 301 instead of 404.

Storing only happens when changes to the URL are made. This does'nt 
happen often.
URLs are just small pieces of data - this won't fill your hdd
Querying this data only happens if an old URL is accessed
