Looks to me that you're hot on the case. Let me know if I can be of help.
If you have any insight as to why some of the universally quantified variables are moved past the class constraint in 8.1 that would be very helpful. Was this on purpose to fix some bug (it's not clear to me if the semantics are different or not), or might it just have been an unintended side-effect of some other change? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12549#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
