I'm not sure what you mean by in band.  The IP address of the BMC is 
assigned via the bios and is different from what the OS later assigns.  
With imiptool we can turn on/powercycle/monitor via the BMC assigned 
address up until the point where the kernel loads.  Once it does, the 
BMC no longer responds.  This doesn't happen with the two linux distros 
we've tried it on.  Wtih both, including SuSE, we can still 
query/control via the BMC using ipmitool.  It seems to be some sort of 
driver issue to me.  I find it confusing that the NIC is shared between 
the BMC and the OS, but I guess that's just how it's done.  Perhaps the 
bsd broadcomm driver is simply blocking this somehow...
