The patch makes no difference. Still get the following results when fusion
is compiled in:

      sdc   74MB/s
      sdd    2MB/s
      sde    2MB/s
      sdf    2MB/s

On second channel:

      sdg   74MB/s
      sdh   74MB/s
      sdi   74MB/s
      sdj   74MB/s

The patch was applied to linux-2.6.13-rc4-git3.

Here part of dmesg output:
