Yes, but also it MUST surely check hardware ID, otherwise how was I able to install fresh, from UPGRADE disc with NO PREVIOUS LEOPARD INSTALL?!. I see your point, but there is no reason for the DVD to NOT check IDs.
[EDIT] I *KNEW* my hunch had something in it!!. See the attached file, unZIP it, and open in Textedit.app or nano/Textmate. The text is too large to copy/paste ALL of it, so I shall only include pertinent portion. This file is located on the UTD DVD @ location: /Volumes/Mac OS X Install DVD /System/Installation/Packages - the file is located inside the installed called OSInstall.mpkg, and is called "Distribution" and you have to unarchive it (using xar -x -v -f OSInstall.mpkg, but not now, because I have done it FOR you, ZIPped it and attached here!).
The installer IS checking hardware IDs, somehow, somewhere - LOOK:

}Once you un-XAR the files from OSInstall.mpkg, you will see that the "Distribution" file is calling another PERL script, called "OSCheck.pl" which must be uncompressed somehow, at install time. You'll find that other PERL file inside the archive named "Scripts" in the same DIR.
