To be honest, it almost sounds like you have a defective input device :)

I had a problem with my old MacBook (the white one in plastic). The battery had expanded and was pushing up on the mouse pad from below. It caused the cursor to jump around when typing. Of course, this occurred in all applications and not only TextMate. But I was mostly using TextMate.
