Hmm.... just tried installing fully updated Rebug TBE (which solves the innitial problem of being unable to patch). Reactpsn didn't work, not 2.0 (not changing the aa profile, so i assume it doesn't work) nor 2.2 (Just launch or launch+triangle = 3.41CFW needed error, launch+circle = theme fix ony? ). I tried using that patch package you provided, manually installing the vsh pack. It didn't give the RSOD but it didn't help the reactpsn either.
I'd say i've either got 2 incompatible game files or I'm doing something wrong (or both).
Guess i'll try redownloading one of the games from a different source and see what happens next.
Thanks for your help.
