Nix, as you've figured out you can 'talk to' the IPMI card over the
i2c bus locally, or over the network.

Could you do an   'ipmitool lan print 1' locally on the box please?

IPMI ports are 623 and  664

Regarding MAC addresses I have seen it both ways - on Supermicro kit
the MAC is the same as the main board IP,
and on Dells and Suns it is different. Actually, I just checked a
Supermicro motherboard and it is different from the mainboard one.
The MAC can be the same in the case of the motherboard having an
on-board bridge, when the IPMI snaffles (technical term) any traffic
on port 623 or 664

Also, as I remember, you sometimes have to permit lan access on channel 1
The commands here are:
ipmitool channel info 1
ipmitool setaccess 1 ADMIN ipmi=-on link-on
assuming you use the userid ADMIN


Have you also had a good look at the BIOS settings?
