CONFIG_DRM_RADEON=y
CONFIG_DRM_RADEON_KMS=y
CONFIG_POWER_SUPPLY=m

causes

radeon_pm.c:(.text+0x13d58f): undefined reference to `power_supply_is_system_supplied'
radeon_pm.c:(.text+0x13e72e): undefined reference to `power_supply_is_system_supplied'


The Kconfig for DRM_RADEON_KMS says:

config DRM_RADEON_KMS
bool "Enable modesetting on radeon by default - NEW DRIVER"
depends on DRM_RADEON
depends on POWER_SUPPLY

Aha. DRM_RADEON_KMS is a bool, so
depends on DRM_RADEON && POWER_SUPPLY
evaluates to y.
