I would strongly suggest you to "upgrade" to a recent kernel from one of 
the listed repos, it can be done without any issues on the guest (except 
that it requires a reboot to load the new kernel), the 3.2 kernel from 
Beng works fine for me on both Debian Squeeze and Debian Wheezy.
Its also possible to upgrade from Squeeze to Wheezy with this repo 
configured without any issues for the guests.

I didnt encounter any specific issues from upgrading from Squeeze to 
Wheezy on VServer containers but you still can hit the same issues as on 
a non container system such as scripts not well coded that doesnt like 
to be ran on php5.4 or htaccess files with deprecated syntax on 
Apache2.4 or custom compiled tools that rely on old versions of 
libraries that gets removed as not used anymore.
One specific point is Dovecot that had some of its configuration 
parameters changed which could make a "simple" upgrade impossible.
