      I wasn't aware of this limitation. Do you know what causes it ? Have you
      informed Beewoolie/Marc of the issue? I cannot imagine why this
      happens, but it should surely be correctable from APEX running in RAM.

      BTW do you boot directly to the kernel in the JFFS2 partition? I really
      like doing that.
