did you checked with ps that Mongrel is the service eating your CPU?

Also, what happens if you run plain mongrel_rails without daemonize or
cluster options?

is the rails application run on production or development mode?

Asking this because sometimes a lot of users (including myself) miss
it in the global picture.

Which patchlevel of ruby you're using?
Also, what is the result if you revert to 1.0.1 version?

Did this happens with a clean, empty rails application too?

We should try other options to see what could be creating the high CPU
use you're getting.
