This appears to be a side effect of setting up info->pixmap in
radeon_set_fbinfo even if accel_cexp is 0. Alternatively to the cited
patch you can also use something like this:
diff --git a/drivers/video/aty/radeon_base.c b/drivers/video/aty/radeon_base.c
index d5b27f9..532e2c5 100644
--- a/drivers/video/aty/radeon_base.c
+++ b/drivers/video/aty/radeon_base.c
@@ -1895,6 +1895,9 @@ static int __devinit radeon_set_fbinfo (struct
