Here is a patch for LCD filtering from SuSE builds.
The patch is from David Turner, one of the freetype2 upstream developers.
David Turner says: "...my final understanding is that the MS patents pretty cover all cases of LCD-specific rendering we're interested in (there are ClearType patents that clearly don't affect us). And by the way, this includes the original LCD-specific code found in libXft, Cairo, and probably the XRender implementation of your X11 Server, even without my FIR-filter patch."
David Turners mails concerning the LCD filtering and the Cairo patch are all on a public mailing list and they explain the problem in detail:
