I don't believe Windows seeing your VM266H as a "Plug & Play" monitor is a problem,
since most NVidia card users will keep that "NVidia Control Panel" software active,
and that software supercedes control of your LCD & Video card over Windows XP.
I'm running Windows XP SR3 fully patched with a cheap NVidia card, and still enjoy
full resolution, multi montior, and portrait landscape control without Windows XP's help.
