Apart from suspend/resume issue, bge(4) still needs more code to
handle controllers with ASF/IPMI firmware.  This part is mostly
undocumented and hard to experiment due to lack of hardware access.
Current IPMI/ASF handling code shows mixed results and setting
hw.bge.allow_asf to 0 will break IPMI support.
