If yes, I would not complain if those ioctl's would return ENOSYS (and do some sensible rate limited logging explaining the issue) in the linux32 on amd64 case but work on i386 (in case nobody has the time to make them work correctly in linux32 on amd64). One question still remains, why is the bitswap required? Is it really that linux uses a different order than FreeBSD and all the other code does it somehow implicitely (and I didn't notice it), or is there something else going on? IMO this is an important question to answer before a commit.
