I got it running on my TR2 also. Performance is good, especially compared to Vista which I kicked off the machine after just one week.
But there definitely are some quirks. It doesn’t ship with a working graphics driver for the 855GM chipset. I found the one from Vista on a forum and got the native resolution to work with it. But when moving a window around, especially VLC or WMP, Windows freezes. At this point, I only can shut it down with the power button.
How did you get your graphics working?
