I hope that this isn't covering old ground, I've been away and haven't been 
able to contribute for a few weeks.

Which version of GnuPG are you using? I thought this was fixed in v1.2.4 so 
that expired signatures can be re-done - it's not exactly a refresh because 
the expired one is still shown on keyservers etc., but a new signature is 
made so that the key can be included back into the web of trust. 

I made a signature on a friend's key before he changed his key expiry date. 
When the main key expired, so did my old signature.  He changed the expiry 
and I used GnuPG 1.2.4 to re-sign the key. Take a peek at 0x8F455606 to see 
the result.

The old subkey is expired, the new one is usable. (This has implications for 
the keyservers that you use too, old keyservers don't like keys like this 
one).

In the snipped signature list, note the expired sigs (X) and the new ones.
