I can't seem to request debuginfo from debuginfod without the full 40 characters.

I suspect changing %pS or updating the "Modules linked in:" line isn't going to be palatable. I've decided to introduce another printk format %pT to print the stacktrace and then updated the architecture code on arm64 and x86 to see how it goes. Other architecures can be updated if this is acceptable. I'll send out a patch series in a little bit that also updates the decode_stacktrace.sh script to parse this.
