I have added code to radeonhd to fetch reasonable chip limits from
AtomBIOS - as this is scarcely documented, I'm not entirely sure
everything is right, though.
So please test latest git master, and check whether the values in the
log printed at
(II) RADEONHD(0): Power management: Raw Ranges
and
(II) RADEONHD(0): Power management: Valdiated Ranges
look reasonable.
There is no behavioral change at the moment, but this is a start.
