Yeah, instead of spending your time and effort trying to get rid of it... By building links to it...
Just make your own pages and outrank it... Normal, basic stuff will be able to do it for you:
- WordPress.com blog post
- Blogger.com blog post
- Tumblr.com blog post
- YouTube.com video page
- Squidoo.com lens
These pages should be fairly simple for you to use and outrank the negative page. They are established sites with huge SEO profiles, so ranking one of their pages is easy.
If you want to bury their page deep, deep, deep... Then you need to do about 20-50 of these and rank them ALL!
