You mean, as in "p-r---"?
Yes, that is normal, and intentional for all ROM module replacements. "p" stands for "pure" and is required for LoadModule as it otherwise does not pick up the file. "r" means that the file is readable, because LoadModule needs to read it.
The files are intentionally not writeable, executable or deletable as removing or altering these files may and will damage your installation.
