[Samba] Possible? Mount vfat, share, have full use of R/A/S/H attributes?

[groups, freeman]

Hi, I've tried a couple of different versions/distros and can't seem to 
mount a FAT32 (vfat) partition and then share it with Samba, such that 
all use of R/A/S/H attributes (for files and folder) is maintained...

So I'm wondering if this is even possible?

I've most recently been testing with
     host: Debian 4.0 (Linux 2.6.18-4-686) which includes Samba 3.0.24
   client: WinXP SP2

Specifically, on the Debian host I have a drive with a FAT32 partition 
and I'd like to share it via Samba. However I find that I don't have 
complete or consistent access to the DOS attributes on files & directories.

What works (I'm doing my testing from the XP client, at the DOS prompt):
    - can create, delete, rename both files and directories
    - in linux by using chmod I can properly effect how the attributes 
appear to the XP client

What doesn't:
    - from XP, cannot apply attributes to directories (get no error msg 
but attribute is not there when afterwards)
    - from XP, applying S or H to files seems to succeed but in fact the 
attributes do not actually get changed on the files
    - when I chmod attributes in linux (and thus on XP client the 
attribs appear properly), then boot the drive in Win98DOS (i.e. no GUI, 
DOS only) only the 'R' attributes is properly handled

At this time I'm wondering if I can expect to be able to use a linux box 
to host a vfat volume with 100% of the FAT attributes supported, and 
keeping the volume compatible with MS operating systems thereafter ... 
i.e. is this even possible?

Thanks in advance for any info or help!

In case I'm doing something glaringly obvious, here's my relevant config:
fstab: /dev/hda6       /mnt/hda6       vfat           
       auto,rw,umask=0000,uid=1000,gid=1000,exec,shortname=mixed     
       0       2

and as a result, mount reports:
    /dev/hda6 on /mnt/hda6 type vfat
    (rw,umask=0000,uid=1000,gid=1000,shortname=mixed)
