Anyways, the d20 Modern Combat Actions table lists getting up from kneeling as a move-equivelant action, dropping to kneeling as a free action. Melee attackers get a +2 to hit you, ranged attackers suffer a -2 penalty.
You may need to adjudicate as to whether or not the rogue gets his sneak attack in, though.
Stand Up from Prone: Use this action to get up when you're lying on the ground. This does not count as movement, but you're pretty darn close to defenseless when regaining your feet, so standing up provokes attacks of opportunity. Getting to your feet when seated on the ground is just as difficult as getting up from a prone position and also requires a move action that provokes attacks of opportunity. If you're kneeling on the ground, getting up takes some time, but it doesn't make you vulnerable, so you use a move action that doesn't provoke attacks of opportunity. Getting up from a chair is a free action that doesn't provoke attacks of opportunity if the chair is fairly high; otherwise it's just like getting up from a prone position.

Here in the old thread was a similar custserv answer... plus the abovementioned houserules.
