It was suggested in IRC that I file a bug here asking for access to the VMware GSX box. So yes, I'd like a system to build x86-fbsd stuff on, in the absence of a real dev machine. It would need to be loaded up with a minimal FreeBSD system; that can be converted easily to Gentoo/BSD.
unfortunately, this box was whacked some time ago because, after several emails to -dev and -core, nobody ever requested access to it. :( You're the first person to ever ask for an account on it.
