I cherry-picked the commit onto 24.10.2 and now PSE is working fine, also it's really nice to have access via /sys/class/poe/.
This is how I did it (disclaimer: I’m not a git expert, so this might not be the best way to do it, but it worked for me):
git clone https://github.com/openwrt/openwrt.git -b v24.10.2 && cd openwrt
git remote add -f mx65_custom https://github.com/mbilker/openwrt
git cherry-pick 38be5c1fca574bf7f3a09bde08b59a4cbd8adfd8
Then I just followed the usual steps to configure and build. this guide was super helpful: https://gist.github.com/chankruze/dee8c2ba31c338a60026e14e3383f981
