I have found that using SMI to change the cpu's frequency on my DELL Latitude L400 clobbers the ECX register in speedstep_set_state, causing unneccessary retries because the "state" variable has changed silently (GCC assumes it is still present in ECX). play safe and avoid gcc caching any register across IO port accesses that trigger SMIs.
