Captain of a DC10 found the APU running when he arrived at the aircraft for preflight and subsequently noted that there was an aircraft logbook entry regarding the APU being inoperative. However, the instructions that accompanied the write-up highlighted the APU problem as shutting down when starting the aircraft engines so ground operation for the cabin environmental equipment may not apply.

Narrative:
Upon reporting to aircraft for preflight, found APU running and supplying pneumatic air and electricity to all busses. Upon later receipt of logbook, observed APU placarded inoperative with write-up stating APU shutdown with engine start attempt. Used ground air for engine start -- balance normal. Since APU was in use at time of receipt, elected to run APU arriving iah for air conditioning on very hot day. APU normal except for load controller made additional demand for engine start.
