There's two ways to go about it.  Since the MoBo is the same, I would run 
quickpkg then copy it over and emerge it on the new disk.

Alternatively, copy over the ebuild and any associated files, then copy over 
the source from distfiles and emerge it as you would normally emerge a 
package.

However, dependencies ...

There are build time and run time dependencies.  The emerge will fail if build 
time dependencies are no longer available on the current portage tree and/or 
fail to run if run time dependencies are missing.  In this case you'll have to 
fish these ebuilds out of the attic and try again.  Some packages will create 
conflicts with the currently installed versions, which may become impossible 
to resolve.  Which is why I originally suggested cloning an already working 
system with all its packages, rather than reinstalling.

Either way, give quickpkg a spin and see where that gets you.
