I suspect (wild guessing really) most systems have a recent enough version of the xrandr library and Wine will be able to load the library fine. However, some drivers (NVIDIA BLOB) only recently started advertising support for >= 1.3 in their release notes. So I guess my question boils down to is if 1.3 xrandr libraries gracefully handle the case where they're matched up with older, less capable, drivers.
Actually, as far as I am informed, previous proprietary NVidia drivers do not have any xrandr support at all. At least xrandr entirely ceased to work on my machine with an NVidia card.
