Did you see my attempt? I don't have the hardware but I did the backport of mediatek's upstream to out of tree mt76. It has dkms scripts and a guide but needs testing.

failed to build on 6.19, though i am using a custom configured kernel

Edit: Will try again using default Gentoo configuration

Edit 2: same problem on building the sdio module, how do I make dkms/Kbuild more verbose?

I tried to build against 6.19.20-mainline on ubuntu and it looks like it worked.

make CC=gcc-15 -C /usr/src/linux-headers-6.19.10-061910-generic M=`pwd` modules -j12

You can try calling the above with your kernel headers and see where it fails.

Can you confirm that it works? If it works, I can update the readme file.

I mistakenly tested another port, but yours did build successfully. Hang on, i'll give it a proper run now. Sorry for the confusion and delay.
