You can see which files are changed in the kb article for each SP/CU. You will see quite a few files have their sizes and versions updated.

Just a quick question, related somewhat, if the mssqlsystemresource.mdf and mssqlsystemresource.ldf cannot be backed up by SQL and I am assuming as SQL has them open, while the service is running, it cannot be backed up to tape, isn't this a point of failure that cannot be easily be remedied whenever the mssqlsystemresource.mdf and mssqlsystemresource.ldf ever become corrupt?

The database serves as read only database and will not be written when SQL Server instance is running.

Like any other file backup, or registry backup, backup of these files too can help you in some extend, but will not help you in service pack upgrades.
This thread is mainly concentrating on the comments of the article.

Yes, but since those only change when service packs/hotfixes are installed, you can just stop SQL as part of the SP installation and take file backups of them.
