How to identify 2005 vs 2000 backups

Can anyone guide me on how to determine if a backup is a 2005 or 2000
database. Is there some identifier bytes I can look at to determine the
correct version.
I have no problem writing a utility to scan a backup file for the correct
info (if it is necessary)
TIA
Rob
On my 2000 server:
restore headeronly
from disk = 'C:\Program Files\Microsoft SQL
Server\MSSQL$SQL2000\BACKUP\Northwind.bak'
results:
SoftwareVersionMajor = 8
SoftwareVersionMinor = 0
SoftwareVersionBuild = 2039
Same in 2005
