If you can get there this route I strongly recommend it. Drilling out and replacing rivets in plastic never works out well.
Do some searching for pictures or videos on the alarm module. They appear to be all the same - (the set up for the S80, XC90 and XC70 I did were the same). That will tell you what you are up against.
Getting the liner out of the way was not too hard.
1. Removed the fasteners on the front edge.
2. Removed two nuts on the backside.
3 Drilled one rivet on the plastic bracket holding the liner to the molding.
4. Pulled the backside over the bolts then down until front edge slipped past the plastic bracket.
5. folded the liner back and out of the way.
Cut a slot on the security bolt. Could not turn it with screwdriver. Cut a edge on the security bolt, then used a hammer and chisel to back it out.
Disconnected the alarm siren and the sunroof came back to life.
Both leads to the battery are burnt in two. Board looks cooked.
