Чтобы узнать совсем они уже устарели или как. Он не может пересобрать их для xorg-server-1.20.0 и размышляет что делать с ними дальше.
Where possible, the driver packages for X11 have been recompiled. However, there were some (xf86-video-geode, xf86-video-tseng, xf86-video-sis, xf86-video-savage, xf86-video-s3virge, xf86-video-rendition, xf86-video-r128, and xf86-video-mach64) that would not compile against xorg-server-1.20.0 and for which no patches seem to be available. Is anyone still using those, or are they finally obsolete? I'll hold off on removing them until I can find out one way or the other.
