`kmutil showloaded` shows address of 0

We have a KEXT that lists an address of 0 when we run kmutil showloaded on Apple Silicon (M1 & M2). The KEXT appears to work fine, but we are concerned that we have something misconfigured.

It shows a proper address on x86_64. Any thoughts would be appreciated.

macOS 13.4.

Cheers, Dave
