I can't upload it (I'm not core dev), but I've created bzr branch:

https://code.launchpad.net/~ivoks/dovecot/lucid

Commits 66, 67 and 68 are required to get everything set up. Commit 69 
would be nice to have, but isn't a requirement.

Commit 66:
- enables use of conf.d and auth.d directories for additional 
configuration. auth.d is needed cause auth section of dovecot.conf can't 
be overridden by additional 'general' configuration file. Fortunately we 
can include configuration file inside the section, overriding everything 
before it. Plan is to move dovecot-ldap.conf and dovecot-sql.conf to 
auth.d/ in Maverick.
- users can now have dovecot with their own configuration options inside 
conf.d/, or they can have dovecot-postfix that will do that 
automaticaly, or they can even have dovecot-postfix with their own 
changes in separate configuration file (exactly the same as apache2 or 
amavisd-new)

Commit 67:
- utilizes changes from commit 66 for dovecot-postfix. On clean install, 
two additional files are installed, one is general configuration in 
conf.d, and the other is auth section in auth.d
- on upgrades, if user changed dovecot-postfix.conf, preinst script 
splits current/old dovecot-postfix.conf file, extracting auth section 
into auth.d directory and rest of the configuration into conf.d. Names 
of those files are the same as those that would be installed by 
dovecot-postfix, meaning that user will be presented with the diff and 
asked for action (replace, keep, merge, etc)
- if user didn't change dovecot-postfix.conf, that file is removed and 
new and clean configuration files are placed in auth.d and conf.d
- NOTE: cause of changes in dovecot's configuration, dovecot won't start 
with old configuration file (this goes for almost *any* configuration 
file, including dovecot.conf and those in conf.d)

Commit 68:
- on upgrade dovecot-postfix wouldn't reconfigure postfix cause backup 
file already exists; this way backup file is renamed. This way user 
could get to his postfix configuration from Karmic even in Lucid or any 
newer version of Ubuntu (on upgrades, old backups are suffixed with 
timestamp)

Commit 69:
- changing postfix's configuration can take some time during which 
nothing is happening and user might get the feeling that something is 
wrong. This patch prints dots while configuring postfix so that user 
knows something is going on.

I've tested upgrades on Karmic->Lucid, with default and edited 
dovecot-postfix.conf and clean install on Lucid. Upgrade from previous 
versions of dovecot-postfix in Lucid also work, but addopting new 
scheme, dropping custom changes is advised (current dovecot-postfix.conf 
file in Lucid's dovecot-postfix package is broken).

If there are any questions, don't be afraid to ask :)
