Thanks for testing :)  Okay I see you patch for that - I'll update my 
patchset accordingly.

Right I'll take a look at that. Am I right in thinking that the codes we 
need to implement are those in Annex B of the IEEE1275 specification? So 
that would be CSI n S, CSI n T and CSI n J?

Yeah. I can fix those, but it requires changing the video struct which I 
can do for a later patchset.
