These are available.

"real" flash is quite different. Soekris (and the PC Engines boards) are a proper subset of i386, and should be treated as such. > For now it seems that everybody who works in this "really small" > area do their own thing, and nobody directly volunteered to try > to do a framework for this kind of thing. > > An important footnote in this area is that we need to exploit the > new generalized WITH_FOO/WITHOUT_FOO build framework to make life > easier for embedded systems when new major feature sets come in. > I intend to maintain the build-option survey to help with this.

I'm looking for the time to get FreeBSD running on the Gateworks Xscale (arm) boards. These are interesting to me for a couple reasons, but the most important is that most of the boards come with a CF socket, which means not having to deal with smaller flash sizes, and/or dealing with a FFS at the FreeBSD level (for now).
