I bricked my dreamplug and haven't been able to revive it yet (I haven't quite given up, but that fact that's it's almost a one-off by being NAND based doesn't help). I just ordered a new dreamplug a few days ago; I assume I'm going to get one with NOR flash this time. When it arrives I'll see about updating and re-validating the patches and try to find someone who'll commit it for us. I'd like to actually have a dreamplug replace the ancient x86 computer I use for router and firewall and etc. But that's essentially putting it into "production," and even if that word may have a somewhat less rigorous meaning when it's a server for a hacker, I still would be happier if the support for it were part of freebsd. The last thing I need when a problem happens (usually in the middle of trying to solve two other problems) is trying to remember where I stashed some big required patchset 2 years ago. -- Ian
