Apple's fork of FreeBSD's ls supports the options -@ and -e to show extended 
attributes and access control lists, respectively:

coreutils ls can detect the presence of an ACL, but cannot display it, and is 
oblivious to xattrs:

Zephyr:~ ril$ /usr/local/Cellar/coreutils/8.22/bin/gls -lFh ~
total 1.5M
drwxr-xr-x    4 ril staff  136 Feb 17 16:06 Applications/
drwxr-xr-x    5 ril staff  170 Mar 31 20:39 Applications (Parallels)/
drwxr-xr-x  156 ril staff 5.2K Nov  9  2011 CS3 Fonts/
drwxr-xr-x   16 ril staff  544 Dec 11 23:35 Classic/
drwx------+  63 ril staff 2.1K Apr 19 14:35 Desktop/

I am currently using a kludgy shim to dynamically switch between BSD and GNU ls 
depending on the passed in flags ( https://gist.github.com/AprilArcus/11124713 
) - it would be great if coreutils supported these features, so that I could 
stop doing this ^^
