What that probably means is that the VirtualBox driver does not support 3D
graphics features (so only one driver should be displayed).  What we should
display is:
1) DirectDraw HAL (equivalent to "Primary display driver")
2) <3D drivers> (currently reports "DirectDraw HAL")

I can easily add a fix that reports roughly the correct driver string, but to
my knowledge there's not currently a way in Wine to detect whether a graphics
card supports 3D graphics features.  Would it be sufficient for your
application to report two display drivers ("DirectDraw HAL" and whatever is
appropriate for the graphics card)?  If the application requests
DDENUM_ATTACHEDSECONDARYDEVICES (which this one does) then, to my knowledge, it
_should_ report more than one driver on any system that supports 3D.
