Yes. 8.2 works out of box. Use mount options acl for
ACLs and user_xattr for EAs.

After quite some experimenting in the beginning (ext3, 
jfs, xfs) it soon became clear that reiserfs is by far 
the best on all counts. I've read postings that xfs 
excells with very large files, e.g. movies, but I 
couldn't see any difference - reiserfs was just as 
fast). It's incredibly fast in directory manipulations,
especially for very large directories with lakhs of 
files. Very parsimonious too. It doesn't compress data,
not yet, but it doesn't waste space like other fs's.
A full reiserfs volume could probably not be restored 
in an equally large ext3 volume. It works since about 
a year impeccably.
