There have been a lot of pullups to the puffs code in the netbsd-5 branch, 
so I recommend you use a 5.1 release candidate.

cd /dev
sh MAKEDEV putter

Check that your kernel config has:

# Pass-to-Userspace TransporTER, required for puffs(4) and pud(4)
pseudo-device   putter
file-system     PUFFS           # Userspace file systems (e.g. ntfs-3g & sshfs)

Correct operation is "no response of any kind on the terminal" - iscsifs 
does not detach from the terminal. On another terminal type mount to see 
what, if anything, has actually happened.

If you are lucky you will see a line like:

/dev/puffs on /xen/iscsi type puffs|refuse:iscsi (nosuid, nodev)

You'll need to compile a kernel with the options in if it not already 
present.
