A number of manufacturers used to sell these kinds of kits. RadTech seems to still do so: http://www.radtech.us/Products/Glides.aspx
The basic idea is to take the titanium covers off the hinges and squirt in "decent lubricant." Don't use WD-40; it's a water displacer, not a lubricant. There are some midgrade oils that might suffice, but I'd go with the RadTech solution, since I've used it myself on a TiBook a number of years ago and it seemed to do well.
