Hi Li,

I am glad that you will develop/test docking support
on your T40, because it should be close to R50p. And
maybe the dock is the same.
I agree that suspend/resume work is more important
than docking.

If you need testing and logs, don't hesitate to let me
know. I can test docking with T41 and R50p for now.

Thanks,
Paul
