Linux seems to have very complex logic to coexist with ASF/IPMI firmware which I don't still understand its implications at this time. bge(4) may need more robust code to handle that but datasheet seems to show very limited information. Lack of ASF/IPMI capable bge(4) controller also make me hard to experiment some code.
