--- Comment #10 from graham <grhm.perry at gmail.com> ---
K, using AMD overdrive in windows it seems in single head mode it steps from
100Mhz to 777Mhz and then 900Mhz, but in dual head it idles at 300 Mhz, but
switches back to 775Mhz and 900Mhz for mid and high. It doesn't seem to use 600
Mhz (ps3) at all, but it's a fairly safe bet that it's the idle state for
triple head, eyefinity stuff.

So the order should be;
single-head: ps1/cm0, ps1/cm1, ps1/cm2
dual-head: ps2/cm(any), ps1/cm1, ps1/cm2
triple-head: ps3/cm(any), ps1/cm1, ps1/cm2

Thanks for the power states. Need cayman, caicos and turks still. Hopefully
they are all the same though.
