Hello, There is also Hal Daume III's port of Binary from nhc98 which has some bit-fiddling features: http://www.n-heptane.com/nhlab/ Not sure if it is better than any of the other suggestions, but I thought I would mention it just in case. (note: the debian directory in there is unofficial for now, possibly broken, and the source / binary package names it generates will be changing soon. But the cabal stuff is reasonably up-to-date.)

you can find Binary.hs in the GHC 6.4 sources (sources of compiler itself) and close to this ByteStream library on my page http://freearc.narod.ru
with help of my library all you need to deserialize data is just:
(sign::Word32, block_type::Int16, crc::Word64) <- ByteStream.readMemory buf bufsize
there is no such easy serialization, i just don't need it because my program uses only low-level functions, but i can add for you something like:
(buf,bufsize) <- ByteStream.writeMemory (sign, block_type, crc)
