I don't see why sleep or hibernation would not be possible. As long as you have swap and the required software, that should be easy. I found what an Amazon seller purports is the wireless card here: http://www.ebay.com/p/lenovo-y50-70-genu...rmvSB=true

Any Linux kernel past 3.10 has support for it, according to this StackExchange thread: http://unix.stackexchange.com/questions/...iye-with-d, and FreeBSD has support according to this thread: https://forums.freebsd.org/threads/42515/page-1

I can't find any information regarding compatibility with any other *BSD.
