Yes. I've been meaning to change that; must get around to it.

Yes. The sequence of operations to force a redraw of the screen works okay under 2.4 but needs 
looking at under 2.6.

Yes. It needs to be atomic (it's the atomic copy) and pages might well be HighMem so I guess the 
answer is to suppress the message rather than changing something in suspend.
