There's not really a generic way but there aren't _that_ many (major) 
Linux distributions.
Redhat and (IIRC) CentOS have /etc/redhat-release; for example:

Red Hat Enterprise Linux AS release 4 (Nahant Update 2)
SuSe has /etc/SuSe-release; for example:

SUSE LINUX Enterprise Server 9 (i586)
VERSION = 9
A Debian system nearby has its version info in /etc/lsb-release .


I'm not sure about the others but there's probably a limited set of files we could check and we'd cover a lot of systems.
