Scott, this is great and for me at least a very welcome project.  

I would  very much like to see the whole power-management stack not only
rationalized, but (again) made as implementation-agnostic as possible.
I guess this means adding suspend2 support to acpi-support?

I would definitely be interested in this.  One reason to use hibernate
is the ease of configuration the script provides -- it would be great if
ubuntu's native scripts had a similar capacity.

I'm glad to see this happening.  I know that Bernard Blackham, the
hibernate author, is interested in assisting in this effort though I
also know he's very busy.  anyway I find this exciting.
