Just a nitpick: Wine does not *use* DirectDraw, it *implements* DirectDraw,
as there's no DirectDraw anywhere other than win32.

I see no problem querying OpenGL, if the extensions can be trusted to
provide useful values - even if they are undocumented or not always
available. The problem with the approach so far seems to be that this
extension is ATI-specific. Then again, the current fallback can be left in
place if Wine does not find a way to properly detect the VRAM amount.

As for asking Xorg, I do not have the knowledge to say if it is feasible -
but one would think that would've been tried long ago if it were
straightforward.
