I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers. Ccing the radeon driver guys.
