Perhaps something like this will work

auto eth1
iface eth1 inet manual

Xen's default bridging has changed several times, and it has caused
some problems for me in the past as well. Plus I needed to use vlans
(have a bridge for each vlan). So I disabled xend's network scripts
(on xend-config.sxp) and setup vlans and bridges manually from the OS.
I'm using RHEL5.3 btw, which is stable so far, and I can complain to
RH's support (although there was never a need to) if I get problems.
