If you want to render more geometry than fits into memory, then only
option is to cache it (if you don't want to leave it to op. sys. swapping).
One paper I know about it could be found:
http://graphics.stanford.edu/papers/displace/
Google should help in finding similar papers.
Other option is to optimize geometry. Latest Siggraph papers ('00 IIRC) 
have number of various optimizations described.
