x11-drivers/xf86-video-ati-legacy is the xserver interface to the kernel 
driver in either graphics/drm-kmod or graphics/drm-legacy-kmod.  It is 
the same as x11-drivers/xf86-video-ati, but an older version, since the 
new version doesn't work with the legacy drm kernel driver. 
graphics/drm-legacy-kmod is only for 12 and later, it is the same code 
that's in base in 11.2 (and 12), with some modifications to handle 
different locations of firmware blobs.
