Missed it in the initial post (hit send too early) - it was 11gR2.
I found something in the documentation that showed me how it should be able
to be done, but I'm getting errors about incarnations that RMAN isn't
Raised an SR with support a few hours ago, hopefully they'll get back to me
tomorrow and just for the sharing of knowledge thing, I'll send the
resolution out when I get it worked out.
Thanks all for your replies to date.

Subject: Re: Using RMAN to recover a copy of a database from backup files
Steve, version of the database is quite important here as steps available to
you vary by version. In addition it sounds like you would be well advised to
engage support on this one. The short and good answer though is that so long
as you have the required backups and arch logs you can achieve your goal.
