Did something change about the command line options that was not documented?

using aufs-base1 i could do this:
mount -t aufs -o nowarn_perm,noplink,udba=none,br:/folder=rw aufs union

but now gives an invalid parameter. This doesnt help either:
mount -t aufs br:/folder=rw -o nowarn_perm,noplink,udba=none aufs union
although it did not give an error, the mount did not succeed either...
