GoodThings - hey man just FYI I have not forgotten about this. I have not had a chance to connect the phone to my computer to take these registry snapshots.
I also thought it worth posting that I tried the v3 driver pack from Neos2007 over at XDA, but saw no difference in anything, including this behaviour with the landscape performance.
I'll try to get the registry snapshots over the weekend if my 2 yr old allows it
