Appears to be patched on latest 13 (Trixie) and even on 12 (Bookworm)

Hello! After a while of leaving my Pi dormant I wanted to jump back in with some crazy overclocking. Followed all your steps as mentioned in the guide, but it appears that it doesn't seem to overvolt anymore.

At first I tried Trixie, no luck, then went to Bookworm where I knew it worked last but still didn't work, leaving me kinda stranded in terms of how to move on. I also downgraded my bootloader back to a version from 6-3-24 and that still didn't appear to change anything.

Any ideas on what the issue may be? If so I'm open to troubleshooting and doing what I can to help.

Start by reproducing the guide's overvolting steps on Trixie and Bookworm, then compare the behavior with the bootloader version from 6-3-24. Done means identifying why overvolting no longer takes effect or documenting evidence that lets a maintainer address it.
