In previous e-mail I already stated that above 2 lines doesn't belong here. 
Driver is responsible for clock rate management.

In previous e-mail I also stated that above changes are not related to GPU 
node and they are also not needed, since HDMI on R40 works without this.

You cleary didn't read rules for patch submission. When you are sending new 
version of the patch, you have to state which version is it in subject line 
and write a changelog below "---" line.
