[on top of rhel5 git, mainline commit 55c9243068db52c7a3a682db10df11e3a6911cd2]

Key lengths were arbitrarily limited to 32 characters.  If userspace is going
to start using the single kernel key field as multiple virtual key fields
(example key=key1,key2,key3,key4) we should give them enough room to work.
