I wonder if it would be a good idea to introduce a platform-independent 'acline' sysctl? Something like 'hw.acline'? For now we could simply have these devices create it. We could do something fancier where AC adapter drivers register with a centralized thingie at some point and it exports a global setting that is true so long as at least one adapter is online. I'm not sure that level of complexity is warranted until we have platforms with multiple AC lines exposed to the OS though. -- John Baldwin
