I think I can explain the difference between the two zaurus benchmarks:

Xscale cpus really need the -mtune=xscale parameter to take advantage of
the pipeline, which AFAIK gcc 2.95 doesn't know about. OZ 3.5.4 also
uses a recent 2.6 kernel (.14 or .15) which has the copy-page locks
removed, so memory access is a lot faster compared to 2.4 and
2.6.<smaller as 14>.

regards,

Koen
