Actually, if we save the addresses of where the modules are in the
persistent ring buffer, and expose the addresses only if they are from
the previous boot (if it's the current boot, it just says "current"),
then we can decipher the modules from the previous boot.  

OK, but when would we save it? it is OK to do it in panic()?

It would be saved in the persistent memory region, and added when a module
is loaded. That is, it will already be recorded when a panic() occurs.
