They cannot be linked, k-x can lock up mirror before opening it's shutter, just enable self timer.
They're still linked. There can be as much time as you wish between the mirror raising and the shutter firing, but every time the shutter opens, whether to make an exposure or to enter live view, the mirror has to raise (and drop first if it wasn't down already) first. It's mechanically linked to the shutter-winding mechanism. This is why, in live view, the shutter can't close and open to make an exposure without the mirror clacking around as well.
I definitely agree with you about the green button though.
fred, I can assure you that that's not a brand-specific problem.

My old olympus (E-330) and canon 40D both had the same low-res preview problem. The K20D is the only camera I've owned so far that did it right, really.
