Here are some of the specific log messages related to configuration changes,
which you might want to search for:

%PIX-5-111002: Begin configuration: IP_address writing to device
     - message generated when new configuration is saved

%PIX-5-111003: IP_address Erase configuration
     - configuration currently stored in memory (or remotely, or wherever)
has just been erased

%PIX-5-111004: IP_address end configuration: {FAILED|OK}
     - request to save configuration either failed or was successful. If it
failed, fix the problem and try again.

%PIX-5-111005: IP_address end configuration: OK
     - exit configuratin mode

[Note: in all these cases, the embedded IP address will reveal whether the
configuration management was performed on the console or through a remote
connection.]

%PIX-5-111008: User <user> executed the command <string>
     - records user actions that changed the PIX configuration 

%PIX-7-111009:User user executed cmd:string
     - records user action that did *not* change the PIX configuration (note
that the message is debug-level)

This same section of the PIX manual includes a number of other useful admin
logs, like reboots etc, that may be pertinent:

Apparently, if you believe the Web documentation, Cisco's Security Manager
offers cross-platform change management capabilities:

I've never tried it, though, so can't vouch for its effectiveness.

Hope this helps -- if I spot other PIX log entries related to configuration
changes I'll post back to the list -- tbird
