The LCT solution times might be more reliable than the Fritzmark scores, the Fritz 5.01 engine ought to be the same you get in the CBM63 update, so maybe you could post some scores for your AMD to check the correlation LCT II / FritzMark? I have used only 12MB hash tables in case your machine doesn't have 128MB RAM ...] Fritz 5 gets 241000 Nps in the long Fritzmark benchmark on my P233MMX (with 98304KB hash tables). That translates to a long/FM of 202.
