In your kernel config file, you need:

vald*           at acpi? # for LCD contrast
radeondrm*      at vga?
options         DRM_NO_MTRR # Crusoe doesn't have MTRR
options         PCI_ADDR_FIXUP
options         PCI_BUS_FIXUP
options         PCI_INTR_FIXUP
options         ACPI_ACTIVATE_DEV

The fourth FIXUP and ACTIVATE are needed because Libretto doesn’t activate all devices after boot.

In my xorg.conf, I setup:

 Option "mtrr" "Off"
 Option "DepthBits" "16"
 Option "GARTSize" "32"
 Option "RingSize" "8"
 Option "BufferSize" "2"
 Option "EnableDepthMoves" "On"
 Option "AccelMethod" "EXA"
 Option "ColorTiling" "On"
 Option "EnablePageFlip" "On"
 Option "RenderAccel" "On"
 Option "SubPixelOrder" "None"
 Option "DynamicClocks" "On"
 Option "AccelDFS" "On"

In order to use full capability of the radeon. DRM acceleration is available only in 16bpp mode. Not enough memory for 32bpp.
