We recently put in a cluster with bonded gigabit, however that was done
using a separate dual-port PCI card.
On Supermicro, the IPMI card by default uses the same MAC address as the
eth0 port which it shares. You could reconfigure this I think.
(lan set 1 maccaddr <x:x:x:x:x:x>
Also Supermicro have a riser card00:30:48:2d:49:44
which provides a separate network and serial port for the IPMI card.
Tyan probably have similar.
