If I dare say it, you were right! I've been testing for about half an  
hour or so (probably a bit more) now.
Still using DEBUG_VFS_LOCKS, and I've tried the test case several  
times, ran an initial backup (i.e. destroy target pool and send|recv  
the entire pool) and a few incrementals. Rebooted, tried it again. No  
panic, no problems! :)
Let's hope it stays this way.

So, in short: With that patch (copied here just in case: http://exscape.org/temp/zfs_vnops.working.patch 
  ) and the libzfs patch linked previously, it appears zfs send/recv  
works plain fine. I have yet to try it with clone/promote and stuff,  
but since that gave the same panic that this solved, I'm hoping there  
will be no problems with that anymore.
