it seems that the driver is able to access memory space (registers, e.g. in radeon_identify_vram() ) but cannot access framebuffer? Please replace '#undef DEBUG' in drivers/video/ati_radeon_fb.c with '#define DEBUG' and also enable CONFIG_VIDEO and use #define VIDEO_IO_OFFSET 0xD0800000 and post the boot log again. Thanks!
