VirtualBox uses Wine's ddraw/d3d infrastructure. It is likely that you tested the new test against an old Wine prior to when this test and fixes were committed.

Your patch contradicts the behavior I saw on a Geforce 7400 Go on Windows Vista, and on a Radeon 9000 Mobility on Windows XP. As such I don't think we should enable GetDC on this format unless we find evidence on a real system that A2R10G10B10 allows GetDC calls. If we find such a system the test should be changed to accept both outcomes(ie, comment out the A2R10G10B10 test)
