It's not a kernel thing, necessarily. Most distros have had xattr
enabled in the kernel for a long time.

It is a filesystem thing. Firstly it needs to be a filesystem that
supports xattr. ext3 and xfs are the main ones, reiserfs also if you
have the patches (which may even be in the main kernel now).

Then it's down to how it works with the filesystem. xfs has xattr
enabled by default and should just work. ext3 has the support disabled
to start with and you have to activate it with mount options. You need
to mount with the user_xattr option, and also the acl option is a good
idea. Put them in fstab, give them to mount with -o, or even set them on
the filesystem directly:

tune2fs -o acl,user_xattr /dev/xxx

Please do, the more tests the better.

Cheers,
