[Samba] samba 3.5.3 time-stamping issue

[Oliver Freyd]

This happens on a amd64 machine, running debian lenny on top of
debian etch (with xen-3.0.3).

The virtual machine that runs samba-3.5.3 runs linux kernel 2.6.18.
Linux samba-fs1a 2.6.18-6-xen-amd64 #1 SMP Fri Aug 21 16:46:08 UTC 2009 
x86_64 GNU/Linux

On another machine I tried debian lenny, kernel 2.6.26-2, no xen, i686 
(32 bit), samba3.5.3 runs flawlessly there.

Somehow setting timestamps is broken by running an old kernel, or on amd64.

Sadly I can't easily upgrade that machine...
