Yes. A related issue is porting GNU 'cp' to Solaris 10 ZFS-style ACLs. These two issues are related. On Solaris, a ZFS-based ACL setup can be trivial even when there are more than 4 ACL entries. I expect this could cause trouble on the Linux-based client of that ZFS file system as well. For the 'ls' port to Solaris I didn't try to figure it all out; I just delegated it to Solaris's acl_trivial function. But to get things working right on the Linux-based client I'd like to have a working setup exhibiting the problem, which I do not have easy access to. One step at a time, though; at least GNU 'ls' works on Solaris 10 with that patch.... By the way, my initial impression is that ZFS-style ACLs are nicer. For example, the shell-command interface seems nicer, with "chmod A..." and "ls -v" rather than the "setfacl"/"getfacl" commands. I hope that GNU/Linux can incorporate these improvements at some point, but it'll require kernel support. One issue is "ls -v", of course: with GNU "ls" -v means something different. That's too bad....
