I thought the TSC problem was fixed in the MII family of Cyrix chips. If so, does this sledgehammer approach take this course of action with the MII? I ask this because I have a PPro 200 ad work, takes 2 seconds for a ping reply, Cyrix MII-300 (Also at work) takes 3-7 (Average of 4 or 5 being the answer). If I remember correctly the time functions are used in networking, and that could explain the difference. The hardware in the Cyrix is much better than in the PPro (except networking and hdrive. They are the same, hard drive is just larger on the Cyrix and no DMA on Cyrix).

P.S. 2.0.35 is what they run.
