[PATCH] wined3d VideoRam registry setting

You can get the amount of videoRam from the x-server log (python script
attached). This is a little unsafe since the video driver is responsible for
logging this info and I don't know if my script works on the format of all
drivers. Also, certain drivers (fbdev) don't output this at all. Then again,
there is no hardware openGL support for this anyway ;-).
Another way to obtain the videoRam would be to use 'lspci -v'.
This is however not error prone either since the the the size reported by
lspci is not necessarily correct.
