It seems this issue is resolved after installing linux-backports-modules. For now I'm going to close this against the linux-backports-modules package. If anyone is still experiencing issues even after trying linux-backports-modules, please open a new bug. This bug already has a lengthy amount of comments so any remaining issues might be better addressed with a new but report. Thanks!
