This is easy. Kill him.
You don't sound as if your character is frustrated. You are frustrated. You, the player. Are the other players frustrated? If so, kill the Rogue Trader. Have yourselves a pow-wow, plot to dethrone him, then kill him. Then tell the player to not draw up another RT.
If the other players aren't as frustrated as you are, then you are in the wrong game. Find another. Errant Knight said this.
I lost you there. So who is frusturated and what the hell are you talking about?
The builders of this forum software put is a button with the word "quote" wrtten on the bottom right side of each post. Use it.
Errant knight is saying that if the OP is unhappy with the way their game is progressing then they should take steps to change it or walk away, the game is meant to be enjoyable.
