Andrew, have you tested the 3.2.0-61 kernel from the proposed channel? These types of bugfix releases can often be helped along with test result comments of the form: "I tried the proposed package and it resolves this problem for me. Hope it is published soon." (or not if it doesn't, which is the most important thing to know if a proposed bugfix package does not fix the bug!)
