I did, only it would for some reason not upgrade the Mesa DRI to 7.0.1, but 6.5.2, which has me confused I must say.

That's what I meant by the "downside". It should be working, and yet it isn't. I'm looking through some recent mesa releases, to see if there's a clue in any of them as to why.

Great effort!
Good news is is it didn't mess anything up, the script itself works as far as I can tell. On the downside it got me no closer to 3D (CN400/PM880).
