That's fixed it!  :-)

Is there a way to do the above permanently - e.g. a kernel parameter
at boot time, or even a custom kernel?  .... and do I lose anything by
doing it (presumably it only affects CIFS mounts)?

Sorry, I didn't realise you meant the one on the non-working system.
It's as follows:-

    samba-client - 3.0.26a-6.fc7.x86_64

I have tried upgrading to the latest Fedora version available:-

    samba-client - 3.0.27-0.fc7.x86_64

but it's still just the same, doesn't recognise the nounix. 

Would a newer samba-client be likely to fix the problem, or at least
allow the nounuix option in the mount command?  How new do I need?

Thanks very much for your excellent remote diagnosis, it's saved me a
lot of hassle.
