Hi Alex.
A year ago, while we were struggling with dpm on Cayman, you implemented a fix
to limit the maximum memory and core speeds to the reference ones in the
clk/voltage dependency tables. Now that Cayman is working great, I'm  wondering
if you would have the time "to dig a bit more internally to try and figure out
how to handle these clks properly" when a card is not using the reference
values? Is there a way to read the maximum speed from the video card bios or at
least to identify a card built to exceed the reference values?

I'm ready to test any patch you can throw at me.

Cheers!
Alexandre
