 I haven't tested it on amd64 at all (hopefully the freebsd32 part 
 compiles :-P), but here is a patch to add a kern_recvit() function and use it 
 to implement freebsd32_recvmsg().  Note that I'm not sure that some other 
 functions like sendmsg() actually work correctly for freebsd32 as they are 
 copying in a 32-bit msghdr and expecting it to be a 64-bit msghdr.
