I could avoid most of the Eq constraints by two modifications:
1. Make Eq a superclass of Scalar. (this requires a major version bump)
2. Replace comparisons like (xs==[]) by (null xs).

Please check, whether the current code works on GHC-7.4:
http://code.haskell.org/~thielema/numeric-quest/

Btw. what code are you packaging that depends on the numeric-quest code?
