Subject: Init data debugging

Would it be feasible to add a kernel debugging option which rather than
discarding init data/code sections just marked the pages as not
accessible, so illegal accesses could be caught ?

Not efficiently. You can memset the pages to an illegal instruction which
does seem to help
