Hi, I updated my trusty R52 ThinkPad to 9.4 - i915. All went quite well.
wifi is unreliable - but that is most probably the same isue I have on the T30 and I am already investigating that with Martin. X11 performance however is close to unusable, even a simple xterm has issues scrolling and there are artifacts in redrawing, sometimes garbage, something wrong colors in the title bar! With 9.3 it wasn't a a gaming platform, but quite usable for terminal and programming. I think that console switch sometimes had it loose acceleration, but it was never so bad and never had artifacts. wscons look and perform fine, the issue is X11.
