Unfortunately I'm not able to replace the kernel since grub in the
domU doesn't recognize my xvda drive.
/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/xvda2.
Check your device.map.
I then inserted "(hd0) /dev/xvda" into the /boot/grub/devices.map but
with no luck.
I'm still getting the bridge-breakdowns. The bridge itself seems to be
up but only restarting the domU helps. "/etc/init.d/networking restart"
has no effect nor does "ifconfig eth1 down && ifconfig eth1 up".
Please help.

Hi,
I'm not sure but I think I suffer under the same problem with a bit
different setup with squeeze testing and xen 4.0rc5.
In fact I'm using bridges in the dom0 and the connections to the domU get
lost sporadically.
In don't see where's a solution to the problem... Is it now a bug? When
it's an iptables bug, where's the corresponding bug in the iptables
bugtracker and what exactly is iptables doing wrong.
You stated "...but as the syslog message clearly indicates this rule works
perfectly when the traffic is bridged."
I'm using bridges but it's not working obviously.
I don't really see any errors in the log below.
Have you tried using different kernel in the domU?
If network is fine from dom0, then this sounds like a bug in the domU kernel.
What kernel are you running in the domU?
