indeed, but I was rather asking this, because it's probably better to look
around for documentation for 9215 then for 9615. Maybe some blocks are going
to be same, but who knows. I should probably download finaly the kernel
sources and look around to find this question myself :-)

Maybe it's the only difference, yes.
