Hi,
This is an issue I've been working on for a while on the Wine side of things and now they have initial support for it. If any of you Win32k/GDI hackers are interested in making ReactOS look a bit better on LCDs please enable support in freetype and review the following Wine patch to get an idea of the requirements.
You might also be interested in how we did it on Haiku: http://www.haiku-os.org/blog/andrej_spielmann/2008-07-23/sub_pixel_antialias...
