Mmm..  I reformatted the reiserfs on the test system to xfs.
Nope, it didn't quite do it.  With options 'defaults,acl' mount still 
gives arror

mount: wrong fs type, bad option, bad superblock on /dev/sda1,
        missing codepage or other error
        In some cases useful info is found in syslog

...and in syslog:

..... kernel: XFS: unknown mount option [acl].

And for the record, when trying with ext2/ext3/reiserfs, the syslog also 
complains:

..... kernel: reiserfs_getopt: unknown option "acl".
..... kernel: EXT2-fs: Unrecognized mount option acl
..... kernel: EXT3-fs: Unrecognized mount option acl

I hope this helps a bit more.
