Ah, also, something else you can try, is replace

	dev_priv->gart_vm_start = dev_priv->fb_location
	    + RADEON_READ(RADEON_CONFIG_APER_SIZE);
with

#define RADEON_CONFIG_MEMSIZE                         0x00F8  
	dev_priv->gart_vm_start = dev_priv->fb_location
	    + RADEON_READ(RADEON_CONFIG_MEMSIZE);

And tell us if it helps ?

Ben.
