Don't use rebase. Set a graft and rewrite the history:

   $ echo $(git rev-parse HEAD) $(git rev-parse HEAD~1500) >> \
		.git/info/grafts

Assuming "first 1500" means the "most recent 1500" commits. But you get
the idea. You can truncate history as well by omitting the second SHA1.
It's very convenient to keep gitk open and File->Reload after each graft
that you set.

When you're done with setting grafts:

   $ git filter-branch -f --tag-name-filter cat -- --all

(You are doing this on a copy of your repository, don't you?)
