Even Wolfowitz disagrees with Rumsfeld on what constitutes excessive interrogation techniques:

Mr. Rumsfeld has said that the American military in Iraq was abiding by the Geneva Conventions, and that the mistreatment was the work of a terrible few. But at a Senate hearing on Thursday, Mr. Rumsfeld's deputy, Paul D. Wolfowitz, acknowledged that hooding prisoners or forcing them to crouch naked for 45 minutes — tactics available to interrogators with General Sanchez's approval under the old policy — was inhumane. The International Red Cross had warned American officials for months that Iraqi prisoners were being abused in American-run prisons.

Friday, changes were announced, likely the result of increased attention to the interrogation methods used by the U.S. against prisoners :

Under a barrage of international and domestic criticism, the top American commander in Iraq has barred virtually all coercive interrogation practices, like forcing prisoners to crouch for long periods or depriving them of sleep, the Pentagon said Friday. The commander, Lt. Gen. Ricardo S. Sanchez, will still consider requests to hold prisoners in isolation for more than 30 days, according to a senior Central Command official who briefed reporters on Friday. The general has approved 25 such requests since October, the official said. But the official said that General Sanchez would deny requests to use other harsh methods. "Simply, we will not even entertain a request, so don't even send it up for a review," the Central Command official said.

....Senator Jack Reed, a Rhode Island Democrat who clashed with Mr. Wolfowitz at Thursday's hearing, said in a telephone interview, "I'm glad they're changing them, but it's like closing the barn door after the herd is out. Why were these regulations promulgated in the first place?"

Unfortunately, the changes only apply to prisoners in Iraq, not Guantanamo or Afghanistan. Once again, here's the chart of interrogation techniques (pdf) currently being employed.
