Just tested with 6970, still fine, no AMD-Vi messages in dmesg.
I have gfxmode/gfxpayload commented out from grub.cfg, maybe that's the difference between your and mine setups.
Maybe, I'll test it later then. After all, I do have gfxmode and gxpayload used in my grub.cfg.
Even with gfxpayload=text (which is working correctly without all the patches), I still have the AMD-Vi IO PAGE FAULT messages.
