Somewhere in /etc (probably) will be a file that lists the release version number.
From the description in the original post it sounds like a failed upgrade. Probably still running the same version.
Seems like a Linux thing. On FreeBSD (I am sure on Solaris as well) running "uname -a" shows everything including the operating system version. On Fedora Core, /etc/redhat-release and /etc/fedora-release contain the operating system version. On other distros and some other unix oses, you can just do "cat /etc/release".
