Why is it showing up in gitk at all?  Does it have its own branch
name?  gitk will normally only show commits that are attached to
something, unless you list a particular commit id explicitly on its
command line.

Once the commits are "detached" correctly, saving the disk space is
kind of unnecessary.  (Most likely the old commits are being held in
the reflog at least, which usually expires in 30 days or so for
safety.)  Moreover, most of the space is probabably space occupied by
the actual files in the revisions, which will be needed when you port
the patches "correctly" anyhow, so there's no point in going through
extra effort to recover the space just so you can use it again.

Have fun,
