  I did it. Kernels are same ones I used in the last report.

  2410-a: backed out both write-back dcache change and clocking-mode
          bits fix in arm9_setup().
          (using sys/arm/include/cpufunc.h:1.29, sys/arm/arm/cpufunc.c:1.65, 
          sys/arm/arm/cpufunc_asm_arm9.S:1.2)

  2410-b: with clocking-mode bits fix in arm9_setup(), and without
          write-back d-cache.

  2410-c: with write-back d-cache chages, and without clocking-mode
          bits fix.


  2410-d: both write-back d-cache changes and clocking-mode bits fix.

  The performance increase was quite obvious.  Thank you for your great
job.

  Do you think we'll have more speed-up if we could actually use
dcache_inv_range?
