Source formatting issues while maintaining code

Hi,

I am currently involved in a project which has a 8 years old code 
base.  New functionalities and some updates to the old code are 
usually done each day with a decentralized team distributed across the 
world (India, UK, NZ, USA)

In the review process if the code is kept with the same formatting it 
becomes easy to check what was added or changed just by a CVS diff. 
(SCM is CVS, No JUnit, Java 1.4 so no annotations etc)

The editor features like Auto formatting the code like in Eclipse and 
NetBeans mess up the diff program and hence we have made a policy not 
to use any auto formatting tool on any code which is already committed 
to the CVS.

I want your views about handling any similar issues with old code 
base.  

We have to live with this code base as it is working and deployed in 
multiple client production servers.

Have any one implemented any creative method to solve this problem?

with regards
Tushar
