Suspend/Resume on Lenovo IdeaPad S400 with FreeBSD 10?

[Adrian Chadd]

Hi all!,

There's a bugzilla ticket for this:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188833

It seems like it's reasonably important; would you mind adding
comments to the ticket that it works or doesn't work for you? That way
whoever doing DRI/Xorg work can see not only the fix but who's been
testing it and on what platforms.

Thanks!
