I don't know much about graphics, or your specific card, but know PCIe cards use GART to access system memory (IOMMU) and AMD in particular uses this for virtualisation too. If it is being loaded as a module I would guess your driver needs it and this will confirm it: $ dmesg | egrep -i 'GART|IOMMU' You can always experiment by unloading it and trying some intensive graphics application, while checking dmesg to see if it is complaining about missing graphics modules. You can try comparative runs on unigine heaven or one of the browser graphics benchmarks and see what results you get.
