Have you tried to use the contents of /etc/issue ? Typically for
RedHat/Fedora this will have the release in it, and (for Sarge at least)
this is also the case for Debian. I've done a dist-upgrade on this box
and the file shows the correct version number at least...
user@debian:~# cat /etc/issue
Debian GNU/Linux 3.1 \n \l
