Two outputs? I got only a Radeon 9600 in the G4 and it does show up as a single
card in lspci (no secondary output). Xorg.log. only shows a single device.

Ok. To rule out influence of other drivers I disabled them (# CONFIG_FB is not
set, # CONFIG_DRM_RADEON is not set) and only set CONFIG_DRM=y,
CONFIG_DRM_OFDRM=y but it made no difference. Sill I get this:
sysfs: cannot create duplicate filename '/devices/platform/of-display'
[...]
of-display: probe of of-display failed with error -22
