  One possible explanation for the performance difference is
the bus bandwidth between main memory and CPU.  If you can
change the bus bandwidth easily, would you run some tests
with different bus setting?  I'd love to see such results.

P.S.
  As you might know, to customize Squeak for StrongARM or
x86 platform, Intel's Integrated Performance Primitives
(IPP) might be useful.  Some sort of computational intensive
operation can be sped up dramatically.  (For example, I
found that JPEG decompression can be about 20 times faster
than current Squeak implementation on iPAQ.)
