LibGGI: as far as I know, not yet. There was some discussion a while
back about implementing YUYV-like pixel formats, but I don't know if
anyone is working on it.
If it is XGGI that you want working, that is a bigger problem since
XGGI accesses the framebuffer directly and therefore someone would
need to add code to XGGI _itself_ to do all the X drawing ops in YUYV
format, and that would be a very big job (AFAIK).

XGGI is indeed a mission since all drawing primitives need to be rewritten,
XGGI does not use GGI primitives but rather uses direct buffer. If you want
to modify GGI to use YUV etc it is much simpler since you only need to
modify core fbdev primitives such as putpixel() getpixel() .
