[PATCH] wined3d VideoRam registry setting

Now that I think about it there's some other issue which is partly related
to this that should be addressed too namely card detection. Right now
wined3d parses sets the card based on several opengl strings. First it
detects the vendor (Ati/Nvidia) and then there are two or three models of
each brand with which it compares the renderer string (contains 'GeforceFX
5900' and so on). Depending on the brand if the card isn't found (which is
the case in most cases) it defaults to a Geforce4Ti / Radeon8500. I know
that for apps running through wine the videocard doesn't matter that much
compared to windows as roughly the same functionality is supported on recent
ati/nvidia cards but some cards use a different 3d backend depending on the
gpu that it detects as  a TNT supports less features than a Geforce7.

The main issue is to connect OpenGL to lowlevel pci stuff as with VideoRam.
In case of a system containing one card this is no issue but in case of
multiple cards it is hard to detect which card is used for OpenGL...
