dmidecode -s system-serial-number

gives me the Service tag number on my host.  RHEL 5, M610...

dmidecode | grep -A4 'System Information' | tail -n1 | awk '{print $NF}'

Dell has done a better job than most vendors in Linux support, and Matt
Domsch in particular is a blessing on the Linux community, but their
collection ought to be called the "Dell Ducktape Repositories". 
Dependencies and obsolescences aren't dealt with consistently, presence
old repo files on a system can wreck the bus (and are not dealt with by
later bootstraps), etc....
