You can enable bapm (append radeon.bapm=1 to the kernel command line in grub)
which may help.  However, it has caused stability problems on some systems
which is why it is not yet enabled be default.  Same goes for some of the clock
and powergating features.  See the settings of rdev->cg_flags and
rdev->pg_flags in radeon_asic.c.
