I didn't realize these chips shut down entirely when they're sitting idle, is that really true? It would be a bit more work than what I currently have in mind, which is to say, buy an industrial grade single-board Intel PC and heat-sink the bujeesus out of the CPU. How fast are these StrongARM chips? It's going to sit idle for a while, but then suddenly I'm going to want to have it talking to three serial ports simultaneously at a pretty zippy pace for a few minutes, then back to idle. I also have a *BSD bias built into me, I find...go with the evil you do know, not the one you don't. This has gotta work! :-) Thanks, Brian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
