Glad it to hear it works :)
For anyone coming here in the (near) future: I’ve just noticed that there’s a corresponding version 550.163.01-4~bpo13+1 in trixie-backports: it is possible that it was patched to work with kernels 6.16+, but I haven’t verified it (I’ve added yet another note to the wiki though ;-] ).
UPDATE: proprietary flavor of 550.163.01-4~bpo13+1 indeed compiles correctly on the 6.17 kernel from trixie-backports. Open flavor still fails. The wiki has been updated accordingly.
