In my opinion that's a no-no. Playing the drums while others try to work or talk is just rude, and I think other musicians (mostly guitarists) need to learn this as well. Set-up time or soundcheck is not the place or time for practicing or trying to impress other musicians or chicks.
I know my kit well enough to just put everything where I need it to be (or close enough) and then a single hit on each piece of the kit will tell me if it needs tuning or if something is loose or similar.
On soundcheck, keep it to a minimum. Slow single strokes until the engineer is happy and a simple groove if he needs to balance the whole kit, and that's it (...now let the guitar wars begin...).
