I did some quick searching, e.g "disable cmov", "disable cmov ffmpeg", "disable cmov mplayer" etc. Have you seen this 2006 patch which appears to include entries to disable cmov in the runtime etc.

I do still own some original pentiums, e.g P120, P133. However at this time I'm just too busy to offer any testing-still remind me in a month or two.
