This is true. These bits are marked as reserved read only bits in 34xx.
I'm fine if you do change here in this patch but I can add immediate
acked-by if you want to post this as a separate change for 2.6.32
(setting them for 34xx is null-op at the moment AFAIK).

If you find generic fix for channel switching problem found also from
older OMAP's like 2420 then I give you a deep bow and acked-by for
2.6.31!
