We'll, I have good news and bad news to report
the bad news
I have not yet managed to get pygame working on the kindle... but I am taking the files from my x64 computer, and trying them. I 1/2 expected them to work, because python is interpreted, but I guess its possible that its using some compiled libraries...
the good news
having hacked my way through a dozen (or more) kual extensions, I have worked out how to execute a python script. So, I'm getting there.
so, watch this space lol.
If I get it working, I'll be sure to add it to the wiki, to help other people in my situation
