No, I think you did everything right.  If I understand it correctly, then 
hw.pci.do_powerstate puts a device into C3 state if no driver attaches. 
That's just what happens here.  That iLO service processor of the DL380s 
shows up as normal PCI device, but exports the console to the network even 
without specific driver (as there is none for FreeBSD), so that it works 
independent of the OS.

So, since there is no driver, the device gets powered down as soon as the 
kernel initializes its ACPI parts, and then the iLO console stops working.

cheers,
