[CentOS] hfs with extended attribute support

Hi all,

I´ve got a HFS+(not journaled) volume connected to my centos6.2 test 
server, i installed the kmod-hfs(plus) packages and read/write works all 
fine.
but since i´m going to use this for serving mac home folders via 
netatalk i would like to mount it with support for Extended Attributes 
and acl´s.
so i add user_xattr and acl to my fstab options but then it fails to mount.
checking the error in dmesg just gives me ¨hfs: unable to parse mount 
options¨.
does anyone know what´s going on and what i should do to make this work?

regards,

Wessel
