Not to worry. The i82802 isn't meant to replace our current random number generator, but rather as a source of entropy for The Bigger Picture (Yarrow). We will still harvest entropy from various interrupts and other system sources. Which brings up another interesting point. Mark, I believe there are still some architectual issues with the Yarrow design. Can you comment on this status? -- Dan Moschuk (TFreak!dan@freebsd.org) "Don't get even -- get odd!"
