(II) RADEONHD(0): Power Management: Known Good Configurations
(II) RADEONHD(0):   1          680000 kHz /   800000 kHz /  1.200 V
(II) RADEONHD(0):   2          110000 kHz /   405000 kHz /  0.950 V

I use
Option       "LowPowerModeEngineClock" "168750"
for 2D & Xv without any problems. And even AtomBIOS table contains
value lower than 250000.

Do I understand my 168750 won't be valid any more and driver will
refuse to use that, until I force it using "-168750"?
