I have been seeing similar issues as well, trying to use more than 1 nic
on a domU with unstable has not been possible for me. If you really want
to crash a domU quick, try to add a vlan to your dom0 and domU share on
a second nic :-)

>From what I have observed you also can't bring a new interface online
after xend has started as well. Meaning add a new ethernet to dom0 than
try to get a domU interface to bridge to it.

What makes you think the peth0 has the wrong mac address? 

On my unstable

peth0     Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
          inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
