+From: Takashi Iwai <tiwai@suse.de>
+Subject: ALSA: hda - Workaround for buggy DMA position on ATI controllers
+Patch-mainline: 2.6.30-rc1
+References: bnc#502733
+
+The position-buffer on ATI controllers are unreliable as well as
+on VIA chips, thus the same workaround for DMA position reading as
+VIA is useful for ATI.
