Hibernate is enabled by default on new installs. It's difficult to
provide for upgrades because it would have to overwrite some existing
configuration. A GUI would be nice, but I'm afraid it's something that I
just ran out of time to deal with. If anyone else would like to take a
look, that would be massively useful.

All network cards should be automatically unloaded/loaded. Please file a
bug if that's not happening.

Suspend will be disabled by default on x86 in Hoary. It's just not
stable enough yet. The resume from disk issue has been dealt with in a
slightly more elegant way that doesn't require any kernel parameters.
