Hmmm - yet when I hit submit on this page, it pushed the GPU up a power level,
and now its stuck there again:
$ cat /sys/kernel/debug/dri/64/radeon_pm_info
uvdvclk: 0 dclk: 0
power level 2sclk: 9

To get more info on this, I rebooted the system with a single screen attached:

Isn't this the reason why there is a multi-monitor power state? same mclk but

problem because there's no memory reclocking happening

In order to switch the mclk, the hw needs at least 450us. The vblank period of
the 1600x1200 mode is 396us, so it's not long enough to switch. The switch has
to happen during vblank to avoid seeing a flicker
